Pursuit (1972)

The ultimate weapon is about to be unleashed!

What begins as a routine investigation quickly escalates into a heartstopping race to save millions from certain death in this taut and gripping thriller. Michael Crichton (Jurassic Park, ER) "makes an impressive directorial debut" (The Hollywood Reporter) in this deadly cat-and-mouse game in which the stakes couldn't be higher! When government agent Steven Graves (Ben Gazzara) investigates political extremist James Wright (E.G. Marshall), he uncovers a diabolical plot to blast lethal nerve gas into San Diego during the Republican Convention. What's worse, a computer hacker (Martin Sheen) has provided Wright with a psychological profile to help him outwit Graves. As Wright ingeniously eludes Graves, can Graves find a way to stop him before the ultimate nightmare begins?
