How does retired cop Joshua Burke (James Earl Jones) get two career criminals, Manny Durrell (Sidney Poitier) and Dave Anderson (Bill Cosby), to follow the straight and narrow?

Accused murderer Frankie Steele walks free, thanks to the efforts of San Francisco defense lawyer Joe Ricco. Then a pair of cop killings strikes the city. All signs point to the newly released Steele as the perpetrator. Has Ricco sprung a killer? Dean Martin keeps his affable ease but abandons his hipster Matt Helm-series swagger to portray Ricco in his final leading-role film, a whodunit mystery set in the city that also was the gritty center of action for the era’s Bullitt and Dirty Harry. Convinced that Steele isn’t behind the murders, Ricco launches an inquiry and runs up against a police lieutenant assigned to birddog him, evidence planted by a racist cop and several assassination attempts on Ricco himself. As the mystery deepens, so does the danger. And behind it all is someone the attorney never suspected. The pre-Laverne & Shirley Cindy Williams plays Ricco’s office assistant.

Five young women vacation together at a resort on an isolated island. They are the resort's only customers and, aside from the boat captain who brought them here and the resort's handyman, Wylie, the island's only inhabitants. When one of the women is found dead, the others begin to fear the captain, who's been acting strangely. Wylie and the captain argue over the identity of the murderer, each accusing the other, and a fight erupts. Alarmed, the women attempt to leave the island, but the boat -- their only means of escape -- explodes and sinks before they can board it. Then Wylie comes to their aid, claiming to have killed the boat captain in self-defense and telling the women they're safe. But are they?
