Easter Island is home to the Easter Bunny's magical workshop--where do you think Santa got all his good ideas? Easter bunny Jr., aka E.B. (Russell Brand), would rather pursue his dream of becoming a rock star than hop along in his father's footsteps. Fred (James Marsden), an unemployed slacker, is trying to figure out what to do with his life when he accidentally injures the soon to be Easter Bunny and decides he's the one to take over the job.

When these two collide, E.B. and Fred both discover what it takes to grow up.
