September 1927, Chicago It took Al Capone three years to hunt down a brilliant but decrepit physicist who owed him a measly $7,000 for one reason: the physicist managed to reverse the aging process, rendering him unrecognizable. But Capone has no interest in this medical mystery. He just wants his money. To recover the debt, Capone orders the physicist's daughter, Justine Bryce, the most successful cat burglar in town, to steal a luxurious necklace from a famous diplomat - while it's still around her neck. Failure will ensure her father's execution. As well as her own. Justine is determined to save her father at all costs. Even if it means trusting a man she is doomed to love forever, a charming but unattainable nightclub owner who trained her as a thief, Vance Flynn. Vance agrees to help, but he has his own reasons for securing the necklace. With only 24 hours to carry out the scheme, Justine needs to steal the necklace while dodging a shrewd but deranged detective who frames her for murder, not to mention double-cross the most vicious gangster in the country...all to avoid ending up on the wrong end of a gun.
