Elizabeth has gone to stay with her sick mother so Reggie uses the opportunity for some afternoon delight with his glamorous secretary Joan, who proves herself to be up for it. Sadly, just as they are about to unleash their passions Reggie is visited, first by his layabout son, resting actor Mark, and then by Elizabeth's right-wing, scrounging brother Jimmy, wanting food. Eventually Joan, hiding from them in Reggie's bedroom, escapes down the drainpipe.
