Can sexual obsession ever lead to love? Messieurs tells the interrelated story of three men, each obsessed with sex in their own way. Monsieur, divorced and solitary, drifts through the cities of France, seeking and seducing women but never connecting with them. He repeatedly returns to the gay bathhouses for sanctuary...until he meets Enid. Back in the USA, Paul is writing a book on the S&M culture. But the characters in his book are stronger than he expected, and they start to become more real to him than his own life. In Canada, Ricardo finds comfort in the brothels and begins to fall in love with a 19 year old prostitute named Haley. All three men find that their obsession with sex, while addictive and dangerous, is their only connection to the possibility of love.
