Only Murders in the Building centers on three strangers who share an obsession with true crime and suddenly find themselves wrapped up in one. In season three of the series – which stars Steve Martin, Martin Short and Selena Gomez – the trio leave their own apartment for the Broadway stage. Behind the scenes, however, there’s been a new murder. Now it’s up to them to crank up their old podcast and, once again, find out who the murderer is.
