An ex-SAS agent and a thief battle for their lives as air runs out in a maze of abandoned mine tunnels while they're searching for $200 million in stolen diamonds.

Through an immigrant cab driver, our world collides with a nervous filmmaker, a lawyer whose new breasts her ex-boyfriend wants to see, a mystery man, a gay man who might or might not have AIDS, and a birthday girl who got stood up. It is a mixture of laughter and sadness, all floating on a sea of philosophy.

The film centres on Ariane, Véronique and Mathilde, three female friends talking over drinks who decide to reveal their innermost secrets, including Mathilde's revelation that she is in love with Ariane and tries to come out to her.
