When Charlie Paczynski's raven-haired partner is caught in the crossfire of a blackmail scheme gone bad, he trails the prime suspect to the brink of Niagara, only to receive a cryptic warning: 'what's happening here you can't begin to comprehend'... Thrust into a world populated by a whiskey-swilling raconteur (Robert Forster), strangely bonded siblings (Matthew Broderick and Camilla Belle), and a dubious government agent (Janeane Garofalo), Paczynski joins the quest for a long-lost design by enigmatic genius, Nikola Tesla.
From the eccentric eavesdropper who gives him his first clue (yes! - that's Robert Vaughn, The Man From U.N.C.L.E.) every door Paczynski forces open raises the stakes. Reminiscent of the conspiracy thrillers of the 70's, complete with a score by David Shire (The Conversation, All the President's Men), and packed with nods to Hitchcock and classic noir, The American Side is a jigsaw puzzle mystery, climaxing under the roar of the Falls as the final piece snaps into place.
