It was written and directed by Trey Parker, who, along with fellow series co-creator Matt Stone, voiced most of the characters in the episode.
In the episode, Kyle finally sees the blockbuster movie The Passion of the Christ and admits that Cartman has been right about the Jewish people all along.
Cartman then uses the film's antisemitic message as an excuse to start his own Neo-Nazi movement disguised as a fan club for the movie.
Meanwhile, Cartman dresses in a brown Hitler-esque uniform, practicing by speaking to the mirror: "Töten sie die Juden.
He suggests that each attendee take one more person to see the film before they begin what he refers to as "the cleansing" — the fan club members obliviously agree.
When Stan and Kenny reach Gibson's house, the director rambles, straps himself to a rack wearing only white briefs and says that no matter how much they torture him, he will never refund their money.
Gibson, wearing face paint from Braveheart, chases their bus in the tanker truck from Mad Max 2, screaming "Qapla'!"
Back in South Park, Kyle talks to Father Maxi about his issues regarding Jesus and the guilt he has been feeling since seeing Gibson's film.
Father Maxi points out that the Passion was originally a play used to stir up antisemitism, but says that its subject matter can still help people.
When he emerges unscathed, Cartman rushes to meet him, but Gibson ignores him and, rambling, first attempts one final time to force Stan and Kenny to give him his money back (which fails, as they refuse), and then smears his own excrement on a building, much to the astonishment of Kyle and the fan club members.
Kyle says he feels better about being Jewish after hearing Stan's speech and seeing Gibson's demeanor, who defecates on Cartman's horrified face and runs off whooping.
