Jamie Dornan and Cillian Murphy fight for their lives as underground operatives against the Nazis in Bleecker Street’s first trailer for the World War II thriller “Anthropoid”, Variety reports.

“Us being noticed gets us all shot,” Murphy’s character explains to his colleagues.

Bleecker Street recently nabbed U.S. rights to the drama from LD Entertainment during the Cannes Film Festival. The movie is based on “Operation Anthropoid,” the code name for the Czech operatives’ mission to assassinate SS officer Reinhard Heydrich in May of 1942.

Heydrich, the main architect behind Adolf Hitler’s Final Solution, was the Reich’s third in command behind Hitler and Heinrich Himmler. He was also the leader of Nazi forces in Czechoslovakia.

The film follows two soldiers from the Czech army-in-exile, Josef Gabčík (Murphy) and Jan Kubiš (Dornan), who are parachuted into their occupied homeland in December of 1941. They must find a way to assassinate Heydrich, with limited intelligence and little equipment in a city under lockdown.

“This operation will involve everyone that we have left in the resistance,” one of the characters notes in the trailer.

Sean Ellis directed from a screenplay he wrote with Anthony Frewin. The film also stars Charlotte Le Bon, Ana Geislerová, Harry Lloyd, Bill Milner and Toby Jones. Ellis, Mickey Liddell and Pete Shilaimon produced.

“Anthropoid” will open the Karlovy Vary Film Festival on July 1. The movie hits theaters on Aug. 12.
