In the hope of winning the woman of his dreams, Amanda, lovelorn meter-reader Roger Wadell enrolls in a secret confidence-building class. The course’s title takes on much more meaning when he discovers that his egomaniacal professor Dr. P also wants the same woman. They begin a fierce rivalry that quickly spirals out of control, their pranks and insults get uglier as they try to prove who is the ultimate guy’s guy.

Hapless Henry Palfrey is patronised by his self-important chief clerk at work, ignored by restaurant waiters, conned by shady second-hand car salesmen, and, worst of all, endlessly wrong-footed by unspeakably rotten cad Raymond Delauney who has set his cap at April, new love of Palfrey’s life. In desperation Henry enrolls at the College of Lifemanship to learn how to best such bounders and win the girl.
