Theo (Reynolds), a small garden snail, is probably the only snail in the garden who is obsessed with speed and racing. Everybody is against it even his older brother, Chet (giamatti). When he accidentally wrecks the garden, he runs off but lands himself in an accident that upgrades him. When he suddenly develops super-speed, he teams up with fake racing snail, whiplash (Jackson) and a team to compete in a challenge he loves-the Indy 500
