Overview
5 Against the House is a 1955 American heist film directed by Phil Karlson and starring Guy Madison, Kim Novak and Brian Keith. The supporting cast includes William Conrad.

The film centers on a fictional robbery of what was a real Nevada casino, Harold's Club.
Plot
Four friends enrolled at Midwestern University (which was fictional at the time of the film but became a reality in the mid-1990s) - Brick (Keith), Al (Madison), Ronnie (Kerwin Mathews) and Roy (Alvy Moore) - visit the Harold's Club casino in Reno, Nevada during a weekend trip.
After an hour spent gambling and socializing, the group prepares to leave. Ronnie, however, has lost money playing roulette and must cash a check at the cashier's window. He is accompanied there by Roy, but unbeknownst to either of them, the cashier is being threatened by a man with a gun. Using a concealed security alarm, the cashier alerts casino officials, who apprehend not only the would-be robber, but Roy and Ronnie as well. Al persuades the police to release Roy and Ronnie, but the inquisitive Ronnie has become obsessed with the idea of a spectacular casino robbery, and he begins forming his own plans to rob Harold's Club after he overhears one of the police officers say "There's no way it [robbing Harold's Club] can be done."
Back at college, the incident is seemingly forgotten, though Ronnie begins developing his plans in earnest. Al also re-establishes his relationship with his girlfriend, Kay (Kim Novak), who recently has become a singer at a local nightclub. Al takes Brick, Roy and Ronnie to see one of her shows. After the performance, Brick, a veteran of the Korean war, is provoked into fighting a fellow student over a former girlfriend, and afterward, he suffers from the effects of a dissociative psychotic episode due to an ongoing battle with post-traumatic stress disorder. Later that night, Al encourages a distraught Brick to return to a veteran's hospital for treatment, but he refuses.
