Cool and sophisticated Tolen (Ray Brooks) has a monopoly on womanizing - with a long line of conquests to prove it - while the naive and awkward Colin (Michael Crawford) desperately wants a piece of it. But when Colin falls for an innocent country girl (Rita Tushingham), it's not long before the self-assured Tolen moves in for the kill. Is all fair in love and war, or can Colin get the knack and beat Tolen at his own game?
