On a mission of vigilante justice, a young woman, Lena, goes to extremes to seek reprisal against a suspected ex-Nazi, in this psychological thriller. Her efforts to extract a confession at gunpoint result in a twisted cat-and-mouse game and a standoff fraught with moral complexities and shocking revelations. Powerhouse performances and a taut script fuel this edge-of-the-seat chamber drama about wartime guilt and culpability across generations.
