Friends play many kinds of games with each other: cops and robbers,
checkers, tag. The best of friends will make up their own games.
Todd and Kevin's friendship is built on such a game. However, the rules
and premise are far from the typical childhood games. A dispute amongst
the two splits them into very different directions: one sees the game
for the cruel act that it is, while the other decides it must move to
the next level.
Imagine No Country for Old Men crossed with Lord of the Flies, or even
imagine if Johnny the Homicidal Maniac were once a little kid. There you
have a Friendly Game.
