Paul and Sophie are planning the holiday of a lifetime, a month-long road trip in Australia, and when they return, they will finally start making plans for their marriage. Then one day a man, Larsen, turns up at Sophie's work. He is from the company's Swedish office and needs her help with legal issues. They work together and he seems to know exactly what a woman wants, making her question her relationship with her fiancé.
Paul meets Marty, a complete stranger, but who seems like a combination of every friend he has ever had. Paul finds himself talking to Marty about deeply personal issues and they bond over similar highly emotional experiences. Then Marty introduces Paul to a world that he never knew existed; a world of willing women, a world where his every desire would be fulfilled.
