While working in a laundromat, the boys find a baby hidden among the linen. They soon find out that the baby, who is the heir to a fortune, has been abandoned by his mother so that her two evil aunts can't cheat her and the baby out of the inheritance. The boys determine to help the woman claim her baby's rightful inheritance from her aunts, who have hired gangsters to find and eliminate the girl, the baby and anyone who helps them.
