When Santa's helper Granny Rose (Mary Tyler Moore) falls ill and must take off a Christmas Eve, she recruits Mr. Grimm (Tony Randall) to help deliver all the toys. What no one but the toys knows is that Mr. Grimm plans to auction off the toys to the highest bidder! His plan means that the toys won't make it to the children who are their destinies. The toys decide to deliver themselves, and the story follows them as they struggle to avoid Mr. Grimm and to find their true homes.
