In a decaying seaside town, a once-popular comedian must face his estranged former partner—a bitter recluse obsessed with their glory days—in a dark comedy about ambition, regret, and the haunting shadows of British showbiz. Billy Bash, once celebrated as Britain’s Third Most Offensive Comedian, clings to his outdated act as his career fades. Decades ago, his family-friendly double act with Clifford Biddle ended in disaster: Billy went solo, and Cliff went to prison.

Now, on the final night of Billy’s tour, he visits Cliff in the storm-battered town of Saltmouth, where unresolved tensions and buried truths resurface. Inside Cliff’s decrepit home, the boundaries between guilt, madness, and the supernatural dissolve, unraveling into a chaotic and macabre nightmare.
