Plot: Steve learns that he has scoliosis and must wear a back-brace for six weeks. Stan gives him advice that it is what's on the inside that counts, but Steve is still ridiculed. Arriving at home early, Steve discovers that Stan is actually bald. Stan explains that when he was a teen, he had a ton of acne and was ridiculed for it. He tried everything to get rid of it, including Satanic rituals. However, before he entered college, he took an experimental acne treatment from guitar lessons, which cures him. Unfortunately, on the second day of college day, the side effect was loss of hair. Stan says that Francine doesn't even know, fearing that she would reject him. Steve calls him a hypocrite. The next day, Stan takes off his wig, only to later get ridiculed at the CIA. Steve encourages him to embrace his deformity. Unfortunately, when he goes to the CIA to implore Stan's co-workers, he sees him in a wind tunnel with his wig on. He later reveals that he never took his wig off; he lied that he was ridiculed at work. Steve then threatens to reveal to Francine about the wig. Stan goes chasing after him, using one of Roger's wigs, making him look like Owen Wilson.
Meanwhile, Roger wins passes to the Chimdale Resort and Spa. After arriving, he reveals that he only won two passes, even though he promised Francine and Hayley (Klaus apparently doesn't count) to come. They end up hiding Hayley in a suitcase, as entry fee is $1,800. However, they draw the suspicion of Ron Turlington. Eventually, the women get tired of sneaking around and decide to leave. Unfortunately, Turlington is watching the front door, so they have to stay cooped up in their room. Francine soon gets stressed, so Roger cricks her neck, only to cause her to fall down. As they get her in a mud bath, Turlington walks in, so they hid Hayley beneath the mud. But she couldn't last long in the mud, so she breaks their cover. Turlington promises not to tell on them, if they help catch a pistachio thief but then realizes that he had rounded up the keys to the vault except himself and Mr. Chimdale. The latter then comes in, proud that he had figured out a complicated mystery he had set for him.
Stan tries to beat Steve to Chimdale but then wonders how he is even getting there. As he pulls over for gas, Steve jumps out of the car boot, thinking they're at Chimdale. He evades Stan and hitches a ride on a tanker truck. But when he gets to Chimdale, Stan tackles him and retrieves his wig. Steve sourly congratulates him; he had got his wig, but he lost his son. Realizing his son means more to him than his hair, Stan decides to reveal his true self to Francine, only to learn that she and everyone else had already known.
