"The Play That Goes Wrong" is a comedic play written by Henry Lewis, Jonathan Sayer, & Henry Shields about The Cornley Polytechnic Drama Society, an amateur theatre group, attempting to stage a play called "The Murder at Haversham Manor". However, as the play progresses, a series of mishaps, accidents, and escalating chaos unfold, with everything from forgetting lines to collapsing sets and disappearing props. The humor stems from the over-the-top nature of the accidents and the characters' attempts to cope with the escalating disaster. It's a classic example of farce, with physical comedy and slapstick.
