Danny McBride plays Fred Simmons, a somewhat competent fourth-degree Black Belt in (what appears to be) ITF-style taekwondo who takes himself way too seriously. Simmons' wife in the film cheats on him twice: first with her boss, and then (after Simmons has forgiven her), a second time with Simmon's idol, a taekwondo movie-star named Chuck "The Truck" Wallace. Simmons' confidence is initially lost but then by the end of the film his confidence is restored. File:The Foot Fist Way - Trailer
