One Life vertelt het inspirerende, waargebeurde verhaal van Sir Nicholas Winton, door wiens inspanningen aan de vooravond van de Tweede Wereldoorlog meer dan zeshonderd voornamelijk Joodse kinderen uit de handen van de Nazi’s werden gered. Jarenlang zette hij en een aantal vrienden zich in om de kinderen veilig naar het Verenigd Koninkrijk te brengen, waar zij veelal geadopteerd werden door Britse gezinnen. Vijftig jaar later, in 1988, verwijt Nicholas zichzelf echter dat hij niet genoeg heeft gedaan om alle kinderen te redden. Pas als het BBC-programma 'That's Life!’ hem uitnodigt om in hun programma te verschijnen, gebeurt er iets waardoor hij eindelijk in het reine begint te komen met het schuldgevoel en verdriet dat hij al vijf decennia met zich meedraagt.
Nee, helaas is One Life nog niet beschikbaar op Netflix in Nederland.
