Helene (Frida Gustavsson) and Carl (Fares Fares) trade their home in Stockholm's archipelago for a sun-drenched villa in Sicily, swapping lives for some weeks with Scarlett (Emma Appleton) and Adam (Jakob Oftebro); a couple they’ve never met. But as they settle into each other’s houses, unsettling details begin to surface. As secrets emerge and hidden betrayals come to light, what started as a picture‑perfect escape slowly warps into a twisted game of surveillance, manipulation and mistrust.
