Archie goes looking for Brenda at Domingo's party -yes, the one he wasn't supposed to attend. Cris scolds him for being an irresponsible zombie and hides him in an abandoned house. Meanwhile, a group of religious ladies are hunting Archie down to "save his soul." Actually, pretty much everyone is looking for Archie, including Sarah Díaz, a rogue investigator with some very unconventional methods.

Díaz questions the students at school while Cris and Brenda try to kidnap Leopoldo-an insufferable guy, but the only one who has the info they need. Archie goes looking for help from the only person nerdy enough to actually assist him. Meanwhile, Wendy and her legion of church ladies stumble upon something that might just save their prayer group. Amen.

Cris has a date with Leopoldo. Eww… or maybe not? Archie's getting dangerously close to losing control and the crew has no choice but to sneak into a crime scene. Brilliant. Bolillo, the dog, might be the key to a cure but an evil force is closing in on him first.

The crew goes to mass. Not to confess but to try and neutralize the zombie threat. Díaz and her "paranormal" ideas are putting her job on the line. The real bitch of it is, if she gets fired, Archie's case will end up in the hands of someone with way less patience for zombies.

Cris and Brenda round up the Mendoza kids to help find Archie. Even Beto, a stoner who never graduated, uploads a video. Gladys, the most religious of them all, sparks a full-on revolution inside the church group. Everything's reaching a breaking point. The crew is forced to seek help from someone unexpected.

Archie knows he's running out of time and wants to finally tell Brenda he loves her, officially ask her out and all that. Meanwhile, Díaz gets a lead that brings her closer to the truth behind the zombie infection, while the crew works on a cure for Archie. But the clock's ticking, and a new alliance puts Archie's life -or, well, his unlife- at serious risk. Will they manage to cure him in time?

The crew bands together to rescue Archie but to do that, they'll have to infiltrate the fortress where he's being held. Brenda turns to an old ally for help and together, Rambo-style, they launch Operation Save Archie before he becomes zombie chow.
