Si No t'Hagués Conegut plot
Eduard, a father and husband, loses his family in a fatal accident. Desperate, he decides to take his own life. Near the site of the accident, he finds a bridge over a train track. Just as he is about to fall over the edge, a woman's hand grabs him and pulls him back. She brings him back to her house and introduces herself as Dr. Everest, a retired NASA quantum physicist who needs a guinea pig — preferably one with nothing left to lose — to test her portal to other universes. Edward decides to agree.
