When he falls ill on his way home from school, 15 year-old Michael Berg is rescued by Hanna, a woman twice his age. The two begin an unexpected and passionate affair only for Hanna to suddenly and inexplicably disappear. Eight years later, Michael, now a young law student observing Nazi war trials, meets his former lover again, under very different circumstances. Hanna is on trial for a hideous crime, and as she refuses to defend herself, Michael gradually realizes his boyhood love may be guarding a secret she considers to be more shameful than murder.
