Steve Railsback, the star of the cult favorite The Stunt Man, carries the ball in Assassin. Railsback plays a CIA agent, assigned to protect a senator. When the politician is killed, the principal suspect is Our Hero. Left to his own devices, Railsback unearths one of those government conspiracies so beloved of quickie filmmakers. While the plot of Assassin is as full of holes as the senator, the action highlights are fine and dandy.
