The First Deadly Sin (1980)

Synopsis
The First Deadly Sin was Frank Sinatra's final starring movie vehicle. Based on a novel by Lawrence Sanders, it casts Sinatra as Edward Delaney, a big-city detective on the verge of retirement. Beset with profound personal problems--including a gravely ill wife (Faye Dunaway)--Delaney nonetheless tackles the case of an axe murderer who seemingly strikes at random. Be on the lookout for an unbilled Bruce Willis. ~ Hal Erickson, All Movie Guide
