As the story opens, nine comedians of various acclaim are summoned to the island retreat of legendary Hollywood funnyman Dustin Walker. The group includes a former late-night TV host, a washed-up improv instructor, a ridiculously wealthy 'blue collar' comic, and a past-her-prime Vegas icon. All nine arrive via boat to find that every building on the island is completely deserted. Marooned without cell phone service or wifi signals, they soon find themselves being murdered one by one. But who is doing the killing, and why?
