In the summer of 1941, Hollywood heats up again when Humphrey Bogart arrives right after a female corpse with a dead bird stuffed inside her overcoat topples into the office of B. Norman Investigations. While filming The Maltese Falcon, Bogie found a mysterious ancient Egyptian hawk artifact on his doorstep containing a mummified black bird. Someone with dark intentions threatens the main cast, one by one, leaving dead birds, from crows to falcons, as their calling cards.

While more murders pile up, jeopardizing the film from being finished, Bogie hires private eyes Babs Norman and Guy Brandt, infuriating his volatile third wife, Mayo Methot, or Sluggy, as she's known in some circles. Unraveling the personal lives of Mary Astor, John Huston, Sydney Greenstreet, Elisha Cook, Jr., Peter Lorre, and Jack L. Warner in their quirky, humorous way, the PIs turn the underbelly of Tinseltown upside down to stop the crazed killer from claiming another victim.
