De Palma's coldly executed techno-thriller opens with a signature sequence: a continuous Steadicam shot starts outside an Atlantic City sports arena, then snakes its way along corridors, up stairs and down an escalator, to reveal the packed crowd awaiting the start of a heavyweight boxing match. We're following flamboyant Rick Santoro (Cage), a corrupt cop who revels in the fact that he sees every angle. Inside, his old pal, Navy commander Kevin Dunne (Sinise), is keeping an eye on Secretary of Defence Kirkland, who has a ringside seat courtesy of arena owner and munitions tycoon Gilbert Powell (Heard). Minutes later, the odds-on favourite hits the canvas, a shot rings out, and Kirkland is fatally wounded. Santoro immediately seals the crowd inside the arena and, using TV and surveillance camera playback, scans the screens for clues as to the killer's identity. As Santoro interviews key witnesses, the film turns into Rashomon with action replays, as we see flashbacks from multiple points of view. The film echoes the technical wizardry and complex plotting of De Palma's best film, Blow Out. Edgy suspense and powerful kinetic energy are generated by the intriguing revelations and razor-sharp editing, while the truth behind its convoluted conspiracy has a surprisingly serious political and emotional undertow.
