Hans Kloss is a fictional World War II secret agent and the protagonist of the 1965–1967 series of 14 live Polish television theater plays titled Stawka większa niż życie (Direct Translation: A Stake Larger Than Life; DVD Movie Translation: Playing for High Stakes; Popular Translation: You Bet Your Life) and the 18-episode 1967–1968 television series of the same name. The TV series was, and still is, widely popular in Poland.
He is actually a Pole named Stanisław Kolicki working for Soviet Intelligence, who impersonates a Nazi Abwehr officer, Hans Kloss, of whom he is a look-alike, in order to wreak havoc inside German intelligence services and armed forces. The switch is accomplished after the real Hans Kloss is arrested for spying behind the Soviet front lines. Following appropriate preparation the look-alike Kolicki is allowed to "escape" back through the front lines and return to Abwehr service. While there, he hurts the German intelligence efforts in various inventive ways. Throughout, he manages to make himself appear trustworthy and advances in German ranks, while at the same time making the Germans suspect each other of being defectors, traitors or agents themselves, often resulting in their execution. The main character starts his espionage work as a lieutenant, promoted after a dozen episodes to the rank of captain.
Kloss is played by Stanisław Mikulski, who became typecast following this role.
The various episodes of the series are unconnected, apart for advancing in time over the period of war; certain actors even return in different roles. The pilot (Wiem kim jesteś - I know who you are) explains the basic premise.
A recurring supporting character is Hermann Brunner, a Sicherheitsdienst officer, played by Emil Karewicz, whom the audience loved to hate. Although Brunner only appeared in 5 episodes out of 18, he usually stole the show. One of his "trademark" sayings was "I hate the sight of a man being beaten... unless I am the one doing the beating".
