Stern, who immigrates to Palestine in 1925 from Poland, becomes active in the Irgun defense organization. After the 1939 British White Paper, which restricts Jewish immigration into Palestine, Stern, along with several followers, refuses to stop fighting against the British and secedes from the Irgun to create a new militant breakaway group, Lehi, also known as the Stern Gang. As a result of his defiant actions towards the British, he quickly becomes a hunted man, with British “wanted posters” showing his photo all over Palestine. He is eventually found and shot by British forces in a Tel Aviv safe house.
