In the city of Rapture, Booker DeWitt is a well known private investigator, handling his clients' dirty work, when not drinking and gambling. On the eve of 1959, a mysterious woman by the name of Elizabeth asks him to investigate the disappearance of a young girl named Sally. Elizabeth's intentions are vague and she is unwilling to reveal any vital information, saying only that Sally is alive and elite artist Sander Cohen may have information regarding her whereabouts. The duo journey to Cohen's at High Street, but are denied entrance to the club. Needing the masks specifically crafted for the club's exclusive party guests, Booker and Elizabeth search the nearby shops. With Elizabeth distracting the shopkeepers, Booker is able to retrieve the required mask and the two are welcomed into Cohen's party.
