The Osterman Weekend

TV journalist John Tanner is coerced by CIA agent Lawrence Fassett, who shows him footage suggesting his three best friends are KGB agents. During their annual 'Osterman Weekend' reunion, Fassett uses extensive surveillance to create paranoia and conflict. This is all part of Fassett's elaborate revenge scheme against the CIA director who sanctioned his wife's murder. The weekend descends into a violent battle, culminating in a live TV broadcast where Fassett exposes the conspiracy.
