[5] During a firefight in the Middle East, American soldier Johnny Talbot is captured by Islamic terrorists and forced to witness the execution of his comrade, Ray.

While she is implementing new, more stringent rules for visa applications of potential terrorist suspects, most of her team are killed while at a restaurant for the birthday of their superior, Bill Talbot.

He delayed attending the party to return to his desk to delete records of the visas he has approved for terrorists entering the United States.

Kate's subsequent attempts to find out the cause of the explosion reveal that Bill was being blackmailed to let certain visa applicants through after Johnny's capture, and the man behind the attack was indeed the Watchmaker.

Kate is forced to sneak back into the embassy to create false passports for herself to follow the Watchmaker to New York, with continuing support from Sam and her friend Sally, the only two people who still believe in her innocence.

Meanwhile, the Watchmaker uses a Steyr HS .50 cal sniper rifle to fire an incendiary round into a sphere filled with explosive gas atop a vacant block of apartments in Tower Hamlets.

Dr Emil Balan is motivated to avenge his late wife's death when her visa to the U.S. was delayed and she did not receive emergency medical treatment in time.

Regé-Jean Page, Antonia Thomas, Jing Lusi and Sean Teale play Kate's colleagues in the visa team: Robert Purvell, Naomi Rosenbaum, Joyce Su and Alvin Murdock.

Paddy Wallace and Parker Sawyers play Johnny Talbot and Ray, two US soldiers in the film's opening scene, while Ben Starr appears as a sniper.

The website's critics consensus reads: "Borrowing heavily from better films in service of a predictable story, Survivor will struggle to sustain the interest of even the most avid action thriller fans.
