One day an alien Spaceship shows up in the sky. They are made of just light and memories and they are looking for the bodies we no longer need so they can inhabit them. After one of them enters in the dying body of Karen, a former professional dancer recently dead, she will try to escape from the authorities and find shelter in the house of her former girlfriend, Sandra. However, after discovering that an alien is inside her lover's body, Sandra will have to decide if she accepts Karen's love or not.
