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. Facing the situation, he agrees to visit a self-help group where he meets a somewhat eccentric masked man who claims to be a time traveler. Rafa starts searching to figure out whether the masked man is who he claims to be and came from the past or is just a mentally ill person who escaped from an asylum.
