A Hollywood studio courts Charles, Oliver, and Mabel to make a star-studded movie based on their hit podcast. But Charles is shaken by another murder in the building: his longtime stunt double, Sazz, was killed in his apartment by a sniper, and her body burned in the incinerator.

Before she died, Sazz had been poking into something about the first season of the podcast. The fatal shot came from the west side of the Arconia, occupied by an odd collection of residents with a secret to hide. Writers, directors, executives and stuntmen also make up the suspect list. Now the podcasters are on a new case: what bombshell did Sazz uncover and who was willing to kill to keep it quiet?

Steve Martin, Martin Short, and Selena Gomez return for season four of “Only Murders in the Building.” This time, the Emmy Award-winning series deconstructs the murder mystery through the lens of film. The movie forces Mabel to ponder how the world views her, and leads Oliver to re-examine his relationship with Loretta. Meanwhile, Charles is racked with guilt that his old friend may have died because of him. As usual, “Only Murders” delivers sly humor, a touch of pathos, and crackling performances by the leads and many guest stars.
