British stockbroker Nicholas Winton visits Czechoslovakia in the 1930s and forms plans to assist in the rescue of Jewish children before the onset of World War II, in an operation that came to be known as the Kindertransport.
During the Blitz of World War II, a female screenwriter (Gemma Arterton) works on a film celebrating England's resilience as a way to buoy a weary populace's spirits. Her efforts to dramatise the true story of two sisters (Lily Knight and Francesca Knight) who undertook their own maritime mission to rescue wounded soldiers are met with mixed feelings by a dismissive all-male staff.
