Dave Dangerous, a 12-year-old soccer crazy Scottish schoolboy and gifted amateur detective, goes on summer vacation to San Diego with his parents. Upon overhearing a conversation about a kidnapping, Dave determines to find the victims. Joining forces with the Four Horsemen of the Apocalypse (whose real names are John, Paul, George and Ringo) and Samantha, the most annoying girl in the world and niece to the missing persons, Dave embarks on a hilarious adventure where he has to, amongst other things, help win the most important soccer game of the year between two Goblin tribes, outwit an Ogre who has delusions of being an actor, survive a trek through the desert and ultimately save the world. Who say's vacations aren't fun?
