Jonathan Craine has left his old life in Hollywood behind him, content to live out his days on a farm in rural California with his teenage son. But when infamous mobster and Las Vegas founder Bugsy Siegel is killed at his home in Beverly Hills, Craine is forced to face his past once again. Summoned to Las Vegas to meet mob head Meyer Lansky, Craine is given the impossible task of finding Siegel's murderers. He has no access to crime reports, no police contacts and no one to help in his investigation other than an ageing hit man and a female crime reporter with her own agenda. But Lanksy's orders aren't to be ignored; if Craine can't find Siegel's murderers in five days, he and his son will both be killed.
