London, 1969. The hottest, hippest, wildest domain of hedonists and pleasure-seekers, where swingers swarm the clubs and discos in a high-stakes quest to live for the moment. At the centre of this decadent scene, one man plays all the angles, never missing a chance to score with the beautiful women who desire him - and walks the line between ecstasy and overload. Now the woman he wants the most knows his number - and may just call his bluff.
