One night in 1939, Josef Kavalier shuffles into his cousin Sam Clay’s cramped New York bedroom, his nerve-racking escape from Prague finally achieved. Little does he realise that this is the beginning of an extraordinary friendship and even more fruitful business partnership. Together, they create a comic strip called The Escapist, its superhero a Nazi-busting saviour who liberates the oppressed around the world. The Escapist makes their fortune, but Joe can think of only one thing; How can he effect a real-life escape, and free his family from the tyranny of Hitler?
