It's "bead season" at slippery rock high. This year the bead-snatching grad game called "Gotcha" has been banned as an official school activity because the teachers have decided to put an end to a dangerous tradition. After paying an entry fee the players are given a bead and someone's name. The object of the game is snatch the bead of your victim and take their name. The winner ends up with all the beads—and all the money.

After the game is banned it becomes even more appealing. The game goes underground and more grads than ever are participating. Katie is reluctant to join in, but as a member of grad council she feels she has to go along.

The game quickly spins out of control. Katie finds herself losing friends and falling victim to her classmates' obsession with the game. She considers dropping out of the game but then devises a better way of getting even with her classmates. Katie finds herself sliding further and further down the chute that leads to disaster. Can she bring a safe end to this deadly game?
