Steve has been chosen to sing the national anthem at the veteran's fair. However, he sings it with little passion, leading Stan to believe that the only way he can truly appreciate the national anthem is by experiencing war. Stan signs them both up for a Vietnam War re-enactment held at a local country club's golf course. Upon enlisting, Steve is immediately put on guard duty but he falls asleep, allowing the Vietnamese to attack their base and capture Stan. Steve goes in on a mission to rescue his father and succeeds. But later, while singing the national anthem at the fair, fireworks are lighted, sending Steve into a "war" flashback. This causes Steve to be committed to a mental hospital. Later, Steve escapes from the hospital as the doctor questions a limbless man named John Q. Mind (voiced by male pornographic actor Randy Spears) on how he opened the curtain. He uses his psychic powers to knock her into the wall as "Mind Quad" goes to commercial. Steve returns to the country club where the re-enactment took place (in a parody of First Blood). He interrupts the golfing, at which a patron tries convincing him to leave, only for Steve to snap again when he sees a spinning sprinkler, thinking of a helicopter and holes up in the golf cart shed. Stan comes in to apologize for pushing him too far and tells him that he can sing the way he wants to. Unfortunately, Steve sings the anthem in an excited mode while wearing a unitard; Stan tells a fellow veteran that he is his neighbor's son. 
 
Meanwhile, Roger wants to gain the code to the Pay-per-view channel to see Barbra Streisand sing the songs of Celine Dion. However, Stan refuses to give it to him (he agreed when he thought it was $4.99, instead it was $499). So Roger joins the Vietnamese side of the reenactment as Stan's warden, interrogating him while he was captured; he tortures Stan by reading the first draft of the Sex and the City film. When Stan gives him a fake code, Hayley soon gives him the real code, in exchange for setting free an Ortolan Bunting, a rare bird, he was planning on cooking and eating. However, he gives her Klaus dressed as the bird. As Roger watches his show, he eats the bird and is so overwhelmed that he experiences the alien equivalent of a DMT trip. 
 
As the credits are rolling, the "Mind Quad" part of the episode returns as a man wearing a black trenchcoat runs into the hospital room. The doctor tells him that John has escaped. The man reveals that John's limbs were not blown off of his body, but into his mind, giving him telekinetic powers. The man vows to catch John as we see John using his mind powers to ride a motorcycle towards the Pentagon.
