A sophisticated London professional discovers that you can't pick your family when the uncouth sister she never knew interrupts her life in an attempt to locate their long-lost father, whom the former had always assumed to be dead. Catherine St. John-Burke (Isabelle Defaut) lives alone in London's Chelsea district. She's obsessed with status, but her recent affair with a married man reveals that she's still not entirely comfortable with her own lot in life. Then there's Shirley Zachary (Emily Corcoran), an uneducated Kiwi woman who never gives a second thought to issues of status and style. When Catherine returns home one day to find Shirley drinking beer in her living room, her first instinct is to scream for help. According to Shirley, the two polar opposites are half-sisters, and their father is still very much alive. Not only that, but in the wake of their mothers' recent deaths, he's currently attempting to make claims on both of their properties. Unconvinced, Catherine takes Shirley to get a DNA test and discovers that her half-sister is telling the truth. But how can Catherine and Shirley ever hope to find their father Jack (Nicholas Bell) when the elusive scammer is hiding out from the mob? Setting out on the trail of a mysterious figure named "Sir Crawford," the girls begin to suspect that they're on the right track and do everything in their power to get rightful ownership of their inheritance.
