A marriage without great financial resources and bad luck wins a little lamb in a raffle. Once they have decided to have it for dinner on Christmas Eve, the couple warn that their children have grown too fond of the animal, now christened as Bolita.
Unfortunately the movie Merry Christmas is not yet available on HBO Max.
