Synopsis by Josh Ralske
Renzo (Julio Chávez) wants to examine the psychiatric files of all students who were treated after the fateful incident, but the files are missing. The killer (Antonio Birabent) is furious at Renzo for foiling his attempt to kill Feldman (Norman Briski). He contacts Laura (Paola Krum) over the internet and tells her that "an innocent will pay" for what Renzo has done. Laura warns Renzo, worried that the killer might target Marcos (Villanueva Cosse). Fernán (Rafael Ferro) surprises the couple and Renzo puts a gun to his head. Shaken, Laura's ex-husband explains that he's been offered a job in Miami, and plans to take their son with him. After that, Renzo calls Carlos to warn him that he might be a target, but it seems the fiend has other plans when Clara, Renzo's transvestite hooker friend, shows up at Carlos's place with a horrific tale of being abducted and tortured by a madman in a hotel room before managing to escape. Renzo and Carlos interrogate Clara about her ordeal. Meanwhile, Martin (David Masajnik) talks to the mother (Esther Goris) of another student, Fernando Spinelli (Alejo Ortiz), the boyfriend of the girl who died in the incident, and learns that Fernando has since become mentally unstable. He calls Renzo with the news. When Renzo says the name "Fernando Spinelli," Clara has a very odd reaction, and quickly excuses herself. Renzo leaves Carlos alone to join Martin in interrogating Senora Spinelli, and they discover that Fernando has a mysterious friend who takes care of him.
