A few days before their anniversary, Mrs. Stotch asks Butters to spy on Mr. Stotch in order to find out what his gift for her will be so that her own won't fall short. While spying, Butters watches his dad enter first a g4y theater and then a g4y bathhouse. Upon returning home, Butters reports to his mother about his father's whereabouts, leaving her appalled by her husband's h0m0 affairs, becoming visibly distraught and unhinged. Mrs. Stotch then attempts to murder Butters by dumping her car in a river with him inside.Hours later, Mr. Stotch enters the home to find his wife attempting to hang herself. He rushes to her side and explains that his tendencies stem from chatting with other bi-curious and married men on the Internet. He insists that he still loves her and doesn't want to lose his family over his "addiction." Mrs. Stotch then reveals to her husband to having drowned Butters. He promises that he will not let her go to jail. The next day, the Stotches confront the press about their son, stating that he was abducted by "some Puerto Rican guy". Here the episode alludes to the case of Susan Smith, replicating the murder method and that a black man is blamed for the act.
As the media centers in on the "missing child" case, the pair are inducted into a club of infamous, highly-publicized characters whose loved ones have also been "taken from them by Some Puerto Rican Guy", including Gary Condit, O. J. Simpson, and John and Patricia Ramsey. They decided to let them into their child was "taken from them by some Puerto Rican Guy" and chant "one of us, one of us, gooble-gobble, gooble-gobble" from the 1932 movie Freaks. Butters however has survived his mother's attempt to kill him. He has no idea this was her intention and brushes it off as an accident, and sets off home, eager to get back in time to celebrate his parents' anniversary with them. First he has to do some singing and dancing at a seedy 'dance' club, and then he has to head down a very scary road. He returns home to find his parents fighting over all the lies they have told, and shocks them that he is still alive. Upon hearing what the quarrel was about, he scolds them for lying and trying to teach him to lie.
Deciding to follow in their son's footsteps, they come clean to the media about the cover-up, revealing many unsettling facts to Butters in the process. Afterwards, Stan, Kyle and Cartman chastise Butters about his unhinged parents. Although he attempts to make light of the situation, Butters admits that he is now probably scarred for life and sometimes lying really can be for the best.
