Two

Dos (2021) — a Spanish horror thriller you can watch online on iFILM. Director Mar Targarona strips the premise to its barest: a man and a woman wake up naked, their abdomens stitched together. Neither knows the other. Neither knows why.

Pablo Derqui and Marina Gatell carry the entire runtime in what is essentially a single location. There is no backstory between them — just pain, distrust, and the slow dawning of who could have done this and for what reason. The reveal is not random cruelty. It is something far more intimate.

At 71 minutes, the film never wastes a scene. It works through claustrophobic psychological pressure rather than gore — closer to a chamber piece than a body-horror spectacle. Stream Dos (2021) on iFILM if you want a horror film where the physical trap is only the surface of the horror.
