This mashup solves the age old dilemma that’s haunted generations of moviegoers: do I watch a Friday the 13th movie or a Muppet movie? After decades of haunting the same camping grounds, Jason is desperate for a change. On the dying suggestion of a bleeding-out camper he just finished slashing into, Jason decides to give the other side of the pond a try for bit. But soon after arriving at a quaint wooded retreat on the outskirts of London, Jason manages to hack up a notorious jewel thief, entangling him in the biggest diamond heist the UK has ever seen. This family-friendly R-rated flick will hit all the important beats, from Jason getting amnesia after a knock on the head to a surprise rescue led by a porcine socialite karate master.
