My Girlfriend's Boyfriend

In the satellite city of Cergy-Pontoise on the outskirts of Paris, young clerk Blanche lands a new job and befriends the lively Léa, who is going steady with Fabien. Drawn to Alexandre, Fabien's friend who is committed to Adrienne, Blanche finds herself strangely invigorated by her encounters with Fabien while grappling with her unspoken feelings for Alexandre. As emotions entangle, she must navigate the delicate balance of love and friendship without losing either, embodying the adage that the friends of friends are one's own, all while seeking a way out of the resulting romantic chaos.
