Javi and his mother are in front of the hospital with a suitcase for staying there for a few days. She’s just suffered a mild schizophrenia episode, but she feels good and she doesn’t want to go in. Javi wants her to enter the hospital voluntarily. Two people with a common enemy, but with opposing goals. Who will win?
