Nadie está loco

Rafa is a lonely teenager with OCD and his overwhelmed mother insists on giving him professional help or he will end up in a military school. Faced with the situation, he agrees to visit a self-help group where he meets a somewhat eccentric masked guy who states to be a time traveler. Rafa begins the search to find out if the young guy is who he says he is and came from the past or is simply a mental patient who escaped from an asylum.
