Retornados

The zombies are stalking again. However, on this occasion humanity has managed to escape the attack thanks to a protein that counteracts the effects and stops some from turning definitively into non-dead. With the epidemic under control, everyone is living in apparent harmony... until the supply of the miracle potion starts to become scarce. Kate, who works at a research center, and her boyfriend Alex, a returned, try to save themselves. (Sitges Film Festival)
