Two entertainers (Thelma Todd, ZaSu Pitts) and the pet monkey they use in their act join a vaudeville troupe. The troupe boards a train to their next destination, and the girls are told to keep the monkey in the baggage car. Not wanting to do that, they sneak the monkey on board, and they (and the monkey) proceed to disrupt everything. This entry in the Todd/Pitts comedy-short series was remade by the Three Stooges in 1936 as A Pain in the Pullman.
