Fan Casting The Confessions of A Movie Star

After the events of the last two films, Sammy has (somewhat) made his comeback in Hollywood, starring in a film that is receiving buzz and premiering at a prestigious festival. However, things come to a halt once a plot comes out about a possible murder on the film's main actor. From there on, Sammy goes back into detective mode and tries to figure out who the killer is before the lead actor gets murdered, with the help of another eccentric actor.
