Count Five and Die is a 1957 British war thriller film directed by Victor Vicas and starring Jeffrey Hunter, Nigel Patrick and Annemarie Düringer.

It was produced by Ernest Gartside with the screenplay by Jack Seddon and David Pursall, based on the non-fiction book of the same title by Barry Wynne.

In 1944 London, Major Julien Howard, a British MI6 intelligence agent, meets Captain Bill Ranson, his new American security officer.

One night, while on a date with Rolande Hertog, the unit's radio operator, Ranson becomes concerned and returns to the offices.

Further, he suspects that Hertog is a German agent; Jan Guldt, their liaison with the Dutch underground, had been sent back to The Netherlands, only to be captured immediately.

Howard sends Piet van Wijt to The Netherlands, supposedly to evaluate the effects of a bombing raid, but actually to test Hertog.

Ranson takes a big gamble, telling her that she did exactly what they wanted her to do and that it was all a "double bluff", then lets her grab a pistol and forces her to shoot him by advancing on her.
