When Zoey and Kiki, two irrepressible girls from another galaxy, land in Lightning Point, their dreams of surfing the waves of Earth's oceans have finally come true. But when Luca finds the key to their ship, the Plasma Card, they're forced to enlist the help of local teen Amber to get it back – a twist with explosive results!

With their space ship obliterated and no other way of getting home, Kiki and Zoey settle into the teenage world of Lightning Point at Amber’s house. Amber’s mother, Olivia Mitchell is surprised by the girls’ appearance, but is glad Amber finally has some company. Amber hopes Kiki and Zoey can keep a low profile, but her dreams are dashed when local surf king, Brandon takes an interest in Zoey and invites her to a barbeque - at the request of girlfriend Madison. At the event, Zoey finds out that Madison is no welcoming party and warns her to keep away from Brandon – but just as the tension between them is escalating, Madison turns on the microwave. The energy pulse morphs Zoey into her true alien plasma form and traps her in an esky! When Amber and Kiki come to visit Luca to talk him out of publicising his crop circle find, Amber discovers Zoey is in trouble – and has to make a fool of herself in front of the whole party to rescue her.

To blend in, Zoey and Kiki start attending Amber’s school – and find it nothing like school on Lumina. In a desperate attempt to contact home, Zoey devises a plan using “primitive” Earth technology. Satellites. Convinced that this plan will work – and will be undetectable to human ears – Zoey and Kiki plant their plasma card on the school satellite and beam up a signal. But when dogs start flooding the school, Amber suspects Zoey and Kiki are behind it – canines can hear the signal. When Piper turns up on the scene as well, Amber takes the only chance she can – before Luca and Mr. Phillips find out the real reason behind the dog deluge.

When Kiki is moved to tears by Amber’s singing, Amber makes an important discovery – Luminans can only experience emotions on Earth. Meanwhile, Zoey has fallen in love with surfing and goes out every day – that is, until Brandon steals her wave and makes her break Amber’s prized surf board…Having never experienced anger, Zoey is a ticking time bomb and when Brandon and Madison team up to push her buttons, Zoey starts creating mini-earthquakes around Lightning Point. Can Amber make Zoey realise that she needs to let her anger out, before she explodes The Diner?

Quadrupeds (horses) fascinate Kiki and when she finds out that Luca’s horse Bandit has been skittish and dangerous to ride ever since they arrived, she feels terrible. Secretly using her alien powers, Kiki reads Bandit’s aura and calms his energy, just in time for Luca to see that Kiki and Bandit now have a special bond. But when Kiki accidentally takes Bandit on a magical ride, she’ll need to tread carefully to convince Luca and Brandon that Bandit is no danger – and still keep her secret. While Kiki is connecting with quadrupeds, Zoey tries to connect with the white goods in Amber’s house – if humans can do housework, aliens could do it twice as fast, and better too! But Zoey will have a lot of explaining to do when Amber returns home to a house full of rampaging appliances

Luca and Kiki have been growing closer and Amber is sick of being stuck in the middle! Finally, Luca asks Kiki out on a date – and Kiki can’t wait. Zoey thinks that love is a waste of time and sets off to follow up on some plasma card research, which may help unlock the mystery of why they came to Lightning Point. When Kiki arrives for the date, Luca is surprised to see what, or who, she brought along. Amber?! Luca is certain that Amber is jealous – and there to spoil the fun. But when Kiki experiences the depth of her feelings for Luca, she starts glowing uncontrollably – and Amber will have to bring the date to an end. Fast. Will Luca buy her excuses?

When Zoey escapes the washing up to recharge her energy, Amber and Kiki think nothing of it – until a big burst of lightning strikes their house. Rushing upstairs, they find Zoey gone. When another bolt of lightning hits the house and tries to communicate with Kiki, she comes to a dark conclusion – Zoey is trapped in the lightning! Luca’s alien hunt has stepped up a notch now that another electrical storm has come to town – the same type of storm as when aliens first visited Lightning Point. After Kiki and Amber lose track of the storm, they realise that to find Zoey, they will have to team up with Luca. Can the girls find Zoey without revealing their secret? Or will time run out when the storm – and Zoey – are blown out to sea?

Queen Bee surfer Madison challenges Zoey to a surfing competition at the most dangerous spot in Lightning Point – the Lighthouse Break. After Zoey wipes out and almost reveals herself to Madison, will Zoey and Kiki be forced to give up surfing for good?

As Zoey, Kiki and Amber head out to the Benedict cane field, owned by Brandon and Luca’s family, Zoey is excited. She can’t wait to show Kiki and Amber the energy anomaly she has found, deep inside the cane. But when Zoey and Kiki test the invisible Luminan energy column with their plasma card, the card’s own energy field is hijacked. After the dust settles, the trio discover – they’re standing in the middle of a huge crop circle. While the girls try to figure out how to cover it up, they hear a whirring noise overhead – what is that? Brandon and Luca have discovered it too – and are flying a miniature plane with a camera attached over the intricate symbol. Luca finally convinces Brandon – this is no human feat. There are aliens in Lightning Point!

With Luca Benedict and Brandon Benedict dangerously close to their secret, Kiki feels that they have no choice but to stick close to them, to find out what they really know. So when Madison throws a birthday party for Brandon, they have no choice but to attend. Madison is hoping to win Brandon back with her spectacular event, but when Zoey and the girls arrive, her hopes are crushed. Brandon and Zoey are finally having some time alone where Brandon admits to her that he’s adopted and feels out of place. Zoey learns they have more in common than she first thought. Caught in the moment Brandon tries to give Zoey a kiss but she backs away and goes back inside.Also, she acts nothing ever happened. While Kiki sticks by Luca, he makes a huge admission – he still has feelings for her! Kiki is swept up in the moment. But when Luca takes her to the crop circle, she thinks the game is up. Instead, Luca kisses Kiki for the first time.

Zoey is sick of waiting and decides to take charge of finding a way home. Back at the cane field, Zoey and Amber test out the energy field one more time. It wasn’t just there to unlock a symbol; it’s a signal pathway that goes straight to Lumina! But while Zoey and Amber are completing their tests, Brandon spies a mysterious energy cloud over the cane field… ALIENS! Before Zoey and Amber can react, Brandon barrels through the cane. Zoey runs, but makes too much noise and gives away her position. She is forced to morph into plasma form to conceal her identity. And now that Brandon has seen the alien plasma light, he is more even determined to catch them. Luca and Kiki are closer than ever and after another magical date, Kiki admits to Amber that she’s becoming almost human – and perhaps a little sad that they’re close to finding a way home.

When a storm is forecast to hit Lightning Point, Zoey and Kiki know it’s time – they can send a signal through the lightning, via the energy field and back to Lumina. The trio is sad that their time together is coming to an end as they prepare to leave. But Luca Benedict and Brandon, buoyed by Brandon’s recent sighting have a plan to catch the aliens. When the storm comes they will be ready. As Amber watches the girls send their signal through the lightning, she stumbles backwards. Energy detectors? Amber tries to call out to Kiki and Zoey – it’s a trap! Luca and Brandon sprint through the cane field towards the energy surge. Suddenly, they’re blasted back by an invisible force – Luca recovers first and sprints on. Kiki discovers too late that they’ve left their plasma card behind and goes to retrieve it, morphing into plasma form. She doesn’t realise that Luca has seen the whole thing. He knows she’s an alien – and he breaks her heart!

With Kiki's cover blown, the girls wait anxiously for a message from Lumina. But when Brandon finds his parents' missing boat mysteriously in the middle of the cane field, there are more questions than answers. Can the girls trust Luca to keep their secret from Brandon, whose parents may have been abducted by their alien ancestors?
