One morning after a particularly wild party, Chrissy and Jo wake up to find Robin sleeping in their bath. He needs a place to live, they need a flatmate that can cook, so they decide to let him live with them. Robin is convinced he's in with a chance with both of them, but he never seems to quite manage to impress either woman enough to get them to go out with him! Further ruining his chances is the dampening presence of landlord George Roper and his wife Mildred who live downstairs.
