When Frank Collins suffers from writer's block, he decides to start a day care for his father-in-law (Danny Trejo) and other seniors as a way to make quick cash, while giving him time to still work on his next book. Eventually getting a small group to care for, Frank soon learns that these are not your typical seniors and they cannot easily be corralled.

When Benny arrives at day care, where the babies are bored, he finds the instruments and soon they are off on a musical journey to the store for a snack.
