Chris has been failing school recently, and Lois forbids him from watching TV until his grades improve. Lois suggests to Peter that he help Chris with his study skills This prompts Peter to lie to her about studying so that he and Chris can watch their favorite television show, Gumbel 2 Gumbel: Beach Justice, a crime drama starring brothers Bryant and Greg Gumbel. However, he is disappointed to discover that the show has been canceled. To get it back on the air, Peter decides to tell the Grant-a-Dream Foundation that Chris is suffering from a made-up terminal illness called "tumorsyphilisitisosis", the symptoms of which include growing extra nipples (actually pepperoni slices) across one's torso, and that being able to watch the show is his dying wish.
Because of this (and because everyone thinks the name of the disease is sexy) an agreement is brokered between Grant-a-Dream and NBC in whichGumbel 2 Gumbel will be put back on the air if NBC can get the film rights to Chris's death. Peter is overjoyed with Gumbel 2 Gumbel back on the air, and Chris uses his "illness" to his advantage in school. However, Peter panics upon learning that mourners are holding a candlelit vigil on their front lawn. When the network comes to claim their part of the deal, Lois finds out about the scam and tells Peter to tell the truth. However, he finds out that he would face jail time for defrauding a charitable organization if he does. Acting out of desperation, he casually claims to have cured him with newfound healing powers and gets off the hook.
Peter gets a reputation for being a healer, and people start worshiping him as a god, which he himself begins to believe; they even go as far as dressing like him and building a giant golden idol of him. Lois and Brian, however, continue to plead with Peter to he admit he is not a god, lest he wants divine wrath bestowed upon him by a real God. It is not long before God himself sends sixplagues upon his house. First a blackout occurs in the Griffin house. Brian then gets covered with fleas. Chris comes down the stairs with pimples all over his face, and while Meg was giving Stewie a bath, the bathtub water turned to blood (much to Stewie's delight). Peter believes that there is a logical explanation for everything until frogs start flying out of his shirt, upon which he finally decides to tell the truth. Though he admits he is not God and begs for forgiveness from the real God, Chris is crushed by the golden idol during the final plague (death of the firstborn son). Peter continues to beg for forgiveness until God, who knows by now that Peter really gets the point, finally ends the plagues and spares Chris' life.
