Toi+Moi – Seuls contre tous, a French new romance film directed by Manon Gaurin, will be available on Prime Video on September 18, 2026. Adapted from Emma Green's literary trilogy, the feature brings together Vittoria Di Savoia and Lucas Barski in the roles of two students forced to collaborate on a film project.
Alma Lancaster is 18 and comes from a wealthy family that assumes she’s enrolled in law. But she’s hiding her true goal: to study cinema and make her own films. On campus, she meets Vadim Arcadi, a 20-year-old loner whose past is hard to pin down.
When they’re forced to team up on a student film, their differences ignite a string of clashes at first. Their rivalry gradually gives way to an attraction they struggle to control, while their family histories and personal secrets complicate how close they get.
This relationship is also under threat from someone who seems to be watching them. Anonymous messages aim to drive a wedge between Alma and Vadim and reveal information that could upend their lives. The film thus fuses the romance universitaire tropes with a spy-thriller vibe built on surveillance and secrets.
Toi+Moi – Seuls contre tous is billed by Prime Video as its first French Prime Original film geared toward the Young Adult audience. The platform is doubling down on literary romance adaptations, after several international productions aimed at the same demographic.
The Toi+Moi trilogy has sold close to a million copies in France, according to Prime Video. The film adapts the first volume, refocusing the story on Alma’s film studies, her forced collaboration with Vadim, and the external threat weighing on their relationship.
Manon Gaurin co-writes the screenplay with Eliane Vigneron and Alix Letribot. The film is produced by Originals by Trésor, a label of Trésor Films, and will be released on Prime Video in over 240 countries and territories.
The project was unveiled among Prime Video Presents’ latest French productions. In the realm of French romances adapted from literary bestsellers, you’ll also find Dear You, along with our guide to the latest streaming films and series.
