The F.B.I.: Silent Partner on AllMovie

The FBI suspects a case of jury tampering when, after the acquittal of notorious mob figure, juror Steven Harber (Robert Hooks) suddenly becomes conspicuously wealthy. Eventually, Harber's conscience kicks in, but it may already be too late. Not only is Harber being shaken down by a blackmailer who witnessed the payoff, but there is also a mob hitman at large who has killed two other jurors in his efforts to make sure that no one talks. Seen as Harber's anguished wife is Cicely Tyson, making the most of a rather thankless role.
