Danny, Chris & Tracy start a hamster raising business. It turns out that hamsters really multiply. When they were going on the road, they can't find no one to take care of all the hamsters. So they take them with them. The hotel doesn't allow those pets, so they have to drive around the block to keep them warm. Shirley tells Danny that he has to dispose the hamsters, so he has an idea. Danny makes a deal with a department store manager to give out free hamsters with a purchase of The Partridge Family's newest album. (thetvdb.com)
