A New Jersey teen dies while filming stunts for a Jackass-like program called "The Dumb Ass Show," and his skull is found to be partially caved in and full of flies. Scully concludes that the flies somehow got in there and ate so fast that his head collapsed from the inside. Doggett suspects the kid's best friend of involvement, but he and Doggett are surprised to see a rash spelling "Dumb Ass" break out on his back due to a lice attack. The principal's son, Dylan Lokensgard, has a crush on the dead kid's girlfriend, Natalie Gordon, but seems to have more of a way with insects. His mother also wants him to have nothing to do with her.
Reyes and Doggett question Lokensgard, since he showed up at the stunts and had a run in with the dead kid's friend; during the questioning, he is swarmed by flies but unharmed. Reyes thinks Lokensgard is, as Doggett calls it, "a horse whisperer for bugs," and the theory seems sound when he is found to be secreting insect pheremones. Lokensgard is quite surprised when Gordon visits him and says she's attracted to him, but she is freaked out when he somehow cuts her mouth as they kiss. The "Dumb Ass" kids confront Lokensgard about the bugs and take him on a ride, but Lokensgard causes the car to crash after disgorging insect-like mandibles from his mouth and spraying them all with webbing.
Lokensgard escapes, and Reyes visits Gordon to get her help in stopping him. He shows up, admitting that he killed her boyfriend so she wouldn't be hurt in the last "Dumb Ass" stunt, and takes Gordon away after webbing Reyes. Scully checks out Lokensgard's house with an entomologist, who gets webbed by Lokensgard's mother. Lokensgard's mother tells her son that she knows about his mutation, which is why she didn't want him going hormone-crazy over Gordon, and takes him away. The entomologist survives, but four other bodies are found in the Lokensgards' attic; as they drive off, Dylan uses his ability to write "I Love You" in fireflies outside Gordon's window.
