Love Nest on Wheels - Buster Keaton, Charles Lamont

Buster is the eldest son in a family of hillbillies who manage a hotel. When Ma announces that the bank is about to foreclose on the mortgage, Buster attempts to raise the necessary $350 by selling a trailer which was left behind by a former guest. Complications ensue when it is found that a pregnant cow has taken up residence in the trailer, but, eventually, Buster is able to relocate cow & calf, sell the trailer to a honeymooning couple, and save the hotel.
