The Apple Dumpling Gang 1975
A convinced bachelor Donovan finds out that he must be delivered with a postal coach. This "something" unexpectedly turns out to be three orphans, his cousins nephews. More precisely, two nephews and a niece, and now they will live with him. Donovan tries to attach the children to the family of one of the townspeople, but the unlucky uncle is clearly more to the liking of the kids.
