Hebrew scripture says, "he who saves one life saves the world entire." At the beginning of World War II, Nicholas Winton was instrumental in the complex relocation of 669 mostly Jewish children, moving them from Czechoslovakia to Britain, the operation known as kindertransport. The true story is fascinating. Director James Hawes's "One Life," the telling of Winton's story, is a somewhat staid but occasionally emotional film that should have nevertheless hit deeper.
