A struggling young writer, Nicholas Whistler, is sent on a seemingly innocent commercial assignment behind the Iron Curtain. On his arrival in Prague, everyone - including his beautiful chauffeuse, Vlasta - believes the Czech-speaking Nicholas to be a spy. It takes much time and adventure for him to realise it, but when he eventually discovers that he has been plunged into the world of international espionage, he is numb with horror. With his contacts gone, he is on his own, and must escape arrest and flee to England. But the secret police are close behind him... Dirk Bogarde stars as replacement agent number 008 opposite Yugoslavian-born screen siren Sylva Koscina in this satirical Cold War thriller. Scripted by Lukas Heller (The Dirty Dozen, The Flight of the Phoenix) and produced by the prolific and highly successful Betty Box, Hot Enough for June also features a supporting cast that includes Robert Morley, Leo McKern and John Le Mesurier.
