A woman and two young homosexuals spend a hectic late night.

Rich, bisexual Thomas makes his way through a swath of lovers of both sexes in Paris. His parents have died, and he doesn't have to work to earn a living, so his days are bacchanalia-filled affairs that run into each other in a hazy bliss. The only one capable of eking out genuine affection from him is his neighbor, Caroline. When she dies and leaves her son in his care, Thomas learns the joys of commitment and selflessness.
