1945: After the thrill and danger of volunteering in an all-female searchlight regiment protecting Londoners from German bombers overhead, Evelyn Bell is secretly dismayed to be sent back to her rigid domestic life when the war is over. But then, she comes across a secret night-time show, hidden from the law on a boat in the middle of the Thames. Entranced by the risqué and lively performance, she grabs the opportunity to join the misfit crew and escape her dreary future. At first, the Victory travels from port to port to raucous applause, but as the shows get bigger and bigger, so too do the risks the performers are driven to take, as well as the growing emotional complications among the crew. Until one desperate night... 1963: Lucy, an unloved and unwanted little girl, is rescued by a mysterious stranger who says he knows her mother. On the Isle of Wight, Lucy is welcomed into an eclectic family of ex-performers. She is showered with kindness and love, but gradually it becomes clear that there are secrets they refuse to share. Who is Evelyn Bell?
