HE’S KILLING ON IMPULSE... AND HE WON’T REST UNTIL HE GETS A CORNER OFFICE

Loyal and hardworking executive Graham Marshall (screen legend Michael Caine) has paid his dues. He has suffered through mounting bills, the indignities of climbing the corporate ladder, and a nagging wife (Swoosie Kurtz, Sisters) with only an anxiously awaited promotion to keep him going. But that all changes when his promotion is instead given to a boorish associate (Peter Riegert, National Lampoon’s Animal House). Annoyed and frustrated, Graham unleashes his rage ... in the form of an accidental killing with which he gets away clean! Emboldened by his newfound talent for murder, Graham begins to rethink his business strategy - with deadly results. Elizabeth McGovern (Ragtime, The Handmaid’s Tale), Will Patton (Remember the Titans, No Way Out), and Jenny Wright (Near Dark, The Lawnmower Man) also star in this electrifyingly pitch-black comedy of Madison Avenue and murder.
