There's something creepy about Brett Bergen's next door neighbor. He's got a greenhouse full of crazy-looking flowers -- and on a dare, Brett takes one and gives it to high school cheerleader Julie Valentine. It was just supposed to be a stupid seventh-grade joke.

But weird things begin to happen after Julie touches that flower. She starts acting really strange, and that makes Julie's boyfriend, superjock Trey Boice, really mad. Brett better look out -- because Trey's got a saber-toothed German Shepherd, Killer, that does anything his master wishes.

Can Brett get Julie back to normal before he becomes dog food?
