Knightfall centers on Ros Knight (Jeanine Nerissa Sothcott), who is unexpectedly dragged into a black ops mission with her MI5 agent boyfriend Hugh (Geoffrey Moore). The pair’s objective is to prevent a deadly bioweapon sale, but when the operation goes fatally wrong, Ros is left with the key to the weapon and a target on her back.

Pursued by a relentless mercenary squad, Ros heads to the country estate of her estranged father, legendary former spy catcher Charles Knight (Ian Ogilvy). As the Knights and Hugh prepare for a terrifying home invasion, sinister forces stalk the corridors of power and the trio must use every trick in the espionage playbook to prevent a homeland security disaster.

Directed by Ben Fortune, Nightfall stars Michael Paré, Ian Ogilvy, Nick Moran, Robert Cavanah, Rupert Holliday-Evans, Jeanine Nerissa Sothcott, Andy Gatenby, Geoffrey Moore, Johnny Palmiero, Joseph Emms, Benjamin David, Harry Walters and Darren Le Fevre.
