Sammy Claws is Santa's cat who longs to help out with his owner's annual deliveries, but is a little disorganised and clumsy. Sammy loves to nap but tends to oversleep. When he dozes off in an empty box on Christmas Eve, he is mistaken for a present, gift-wrapped and loaded on to Santa's sleigh.

Sammy wakes up startled and disoriented, but for once his timing is perfect. He rescues Santa's sleigh from a pair of crooks with nefarious intentions. Sammy saves Christmas and proves he's more than capable of being Santa's companion on the most important night of the year.
