The one that started it all! Allen Strange stows away on a ship from his planet and winds up stranded on our planet. Good thing Robbie and Josh are around!

Is it safe for Allen to go places on his own? Robbie doesn't think so. She goes to look after him and ends up putting herself in danger!

The Stevensons discover that Allen isn't the only intergalactic visitor to drop by Planet Earth... and the new alien on the block isn't very friendly.

Allen really, really wants to get back home. He sends out a signal to his home planet, but Shaw and Phil Berg track the message.

Before Phil Berg can capture Allen, the Trykloids capture Phil. But the A.R.C. has better luck, and now Allen is behind bars with only one hope of escape.

Josh isn't only into UFOs, he's into ghosts too--especially after he and Allen actually MEET one. Meanwhile, Ken and Robbie try to rewire the house.
