Rodney's father left, so he and his mother struggle to get by. When his well-to-do aunt and uncle decide to take a three months' long cruise, his cousin Blake is sent to go to high school with him. It's bad enough that Rod has to share his tiny room with his cousin, but when Blake finally arrives, it is with a ton of stuff and an attitude that Rod should be his servant. Rod, who is very busy with his band, Fanged Grapefruit as well as his girlfriend, Audrey, isn't pleased. As Blake does more an more sneaky things to Rod, he also tries to ingratiate himself with all of Rod's friends, to the point where Blake throws animals guts in his own face so he can blame it on Rod! On the other hand, he gets some awesome gigs for the band, but he also turns Audrey against Rod. His head spinning, Rod isn't sure what his cousin's evil plan is, only that it is evil, and he must find some way to stop him, even if it is by sort-of kidnapping him and attempting to drive him across the country! Will the cousins ever be able to make peace?
