Knucklehead is a knock-out comedy in the vein of Blades of Glory, Happy Gilmore or Dodgeball. Set in the very popular and exciting world of Mixed Martial Arts (MMA), our story follows a low-rent con artist named Eddie Sullivan. After incurring a large debt with a local criminal ringleader, Eddie creates a get-rich-quick scheme and enlists a sweet gentle giant named Walter as his unwitting accomplice. Eddie's plan: travel from town to town with Walter and enter small, unsanctioned MMA fighting competitions for prize money. Walter's orphanage - the only home he's ever known - also needs funds desperately, so he reluctantly agrees. During their journey, Walter discovers what life is like outside the orphanage while Eddie becomes morally conflicted over whether to take all the loot for himself or keep his promise to Walter, the one person he can actually call a friend.
