New thriller The Girlfriend has just landed on Prime Video and out of everything new on Amazon's streamer in September 2025, this one is the most heart-stopping. Fronted by Robin Wright and Olivia Cooke, the story follows Laura (Wright) meeting her son's new girlfriend and instantly believing that all isn't what it seems. Basically, there's a lot of cringe mommy's boy stuff happening throughout the series.
The main twist is that every episode has a dual perspective – we see the same situations play out from both Laura and Cherry's (Cooke) point of view, meaning we never know who is a reliable narrator and who isn't. Add to this a plethora of steamy scenes, near-death experiences and life-changing secrets, and you've got a binge you can't miss.
