After a hurricane, John B, JJ, Pope and Kiara plunge headlong into danger and adventure when they find a mysterious sunken wreck.

Convinced that the clue found onboard the boat connects to his missing father, John B leads his friends on an increasingly frantic search for answers.

As the gang hatches an illicit scheme to get to the bottom of the deep-sea mystery, John B confronts Sarah while Pope jumps at the chance for revenge.

When John B's supervision-free home life catches up to him, he receives a well-timed assist — and some spiffing up — from the last person he expects.

John B believes he's made a breakthrough in the hunt for the gold, but his desire to include Sarah in the quest causes friction among the friends.

JJ's reckless behavior ramps up when the friends try to score some quick cash. Meanwhile, John B grows closer to Sarah — and makes her dad suspicious.

John B finally learns the truth about his dad — and sets off a chain of events that jeopardizes everything he and his friends have fought to accomplish.

With his options dwindling and enemies closing in, John B looks for an exit plan. Sarah feels pressured to pick a side. Pope lets his emotions out.

An island crawling with law enforcement and a looming tropical storm are just two of the obstacles facing John B as he tries to make his escape.
