Big Heat (Criterion) 4K UHD 06/25 Blu-ray (Rental)

Honest police detective Dave Bannion is investigating a brutal gang he believes has the police force in its grip. A fellow officer's suicide and the suspicious quiet of his colleagues convince him the corruption reaches into his own department. When a bomb intended for Bannion kills his wife instead, he turns into a relentless avenger, helped by Debby, the discarded girlfriend of a gangster. Drawn ever deeper into the underworld's vicious snare, the pair will do whatever it takes — even kill — to expose the truth.
