 In a smoke-filled dive in Buffalo, NY, David Marx tells us his tale of obsession, betrayal, and murder - leading him to an uncertain fate "underneath Niagara Falls." David tells us how his beautiful redheaded ex-girlfriend, Jennifer Barnes, has disappeared and how he ended up the guardian of the 2.5 million dollars that "was supposed to have bought Jen s safety." Three nights ago, David finds police detectives Crane and O Keefe trashing his apartment. Taking him to Police Headquarters, they interrogate David about Jennifer s disappearance, and Crane - in the name of Jen s father, the rich and powerful Ethan Barnes - brutalizes poor David in hopes of getting a confession out of him. When falsely accused, what s a film noir hero to do but search for the truth himself?
