Lady of Vengeance

When publisher William Marshall (Dennis O'Keefe) learns his young ward Melissa Collins (Eileen Elton) has committed suicide, he sets in motion a plan to murder the man who drove her to kill herself. Mistakenly believing that singer Larry Shaw (Vernon Greeves) is his intended target, Marshall unwittingly seeks help from the man who actually broke Melissa's heart, criminal Emile Karnak (Anton Diffring). When Marshall learns the truth, however, he turns his efforts toward Karnak instead.
