Following a series of supernatural events, Catalina realizes that their "link" is stronger than ever and that her sister Agata is screaming for help from her unconscious state. Catalina is now determined to find out what really happened to her sister in order to help her wake up. Nuno, Agata's long time friend, and Omar, Catalina's boyfriend, agree to help her.
