Vera Keyes Vera Keyes was a pre - War starlet for whom Frederick Sinclair built the Sierra Madre Casino . Background . Vera Keyes was a well - known Hollywood starlet before the war , whose claim to fame was a number of poorly - written romances that drew in large box office crowds and poor reviews , such as " Love Sets Sail ! " She was one of the celebrities invited to the Grand Opening of the Sierra Madre Casino . Of all the guests there , she had a special connection to the casino - she was the inspiration for its construction by its founder , Frederick Sinclair . Sinclair worshipped the ground she walked on , and built the casino as both a monument to her and a fortress to protect her . Sinclair wasn ' t a stupid man ; he could see the war on the horizon , and he wanted his love to be safe from it . So he built the Sierra Madre , with its vault as the ultimate nuclear fallout shelter , for him and his love . Vera ' s voice was the key to the casino ' s vault , specifically , the words " begin again " and " let go " , spoken in her voice into a specific terminal in the casino would activate the elevator down into the casino ' s bowels . Dean Domino , an old flame of Vera ' s , introduced her to Sinclair after seeing that she had caught his eye . But things are never simple . Dean had grown resentful of the other man and decided to take everything from him , and Vera had agreed to help with his plan . When she later started to get cold feet , he secured her assistance by blackmailing her with evidence of " indiscretions " and addictions to and s . What he did not know was that the addictions stemmed from her taking the drugs as pain relief , a refuge from a terminal illness . Vera , eventually overcome with guilt , told Sinclair of the plot . Although he had long known of her and Domino ' s intentions , he had managed to bear that fact . But this knowledge blackened Sinclair ' s heart , and he turned the vault into a trap for Domino , making it impossible to leave so that he would have an eternity to contemplate his betrayal . Sinclair eventually relented , and attempted to return the casino to its original purpose , but this proved impossible - it had been built simply too well . He did what he could and hoped that after the doors to the vault locked , the Sierra Madre Broadcast , the casino ' s emergency signal , would bring help from the authorities and unlock the vault ' s treasure - Vera . On the night the bombs dropped , the night of the Grand Opening , the casino locked its doors and its security systems activated . The s massacred the guests , and Vera was trapped in her room , with only one way out . She wrote her last words on the wall , and took an overdose of the chem cocktail which had both saved her from and caused so much pain already . A malfunction with the Emergency Broadcast , something to do with the Gala Event drawing power from the security systems to save money , caused the advertisement for the casino ' s grand opening to be sent across the airwaves , rather than the intended broadcast . For over two centuries , Vera ' s voice would act as bait , not for the rescue Sinclair had hoped for , but for potential treasure hunters , luring them to their deaths , urging them to come to the Sierra Madre - a place where they could begin again .
