For the past few years, the kids at summer camp around Black Lake have played a game of war against each other. The richer northern group against the poorer southern group. Things get complicated, however, when the leader of the indian clan, Julian, falls in love with the opposing leader's sister, Sarah. At night when the 'war' has ceased, the lovers meet. But this year, the battle between the camps will become all too real when Sarah's brother, Marc, decides to ignore the rules of war.
