Officer Bannerman is a rookie and the other officers play pranks with her. When the Cajun serial-killer Duane "Eater" Mello is brought to the police station, officers Bannerman, Marty and Mattingley are assigned by Sergeant Wiliams to spend the night in the precinct watching the killer to deliver him to the FBI in the morning. The Eater used to eat parts of his victims and is locked up alone in a cell. However along the night Bannerman learns that Duane is very powerful and capable to switch bodies with the victim that he has eaten the heart.
"Eater" is so far the best episode of "Fear Itself", with a creepy story. The tale is claustrophobic and scary and the conclusion is well-resolved. My vote is seven.
Title (Brazil): "Eater"
