On D-Day, a mixed group of forced labourers held by the Nazi forces take shelter from a bombardment inside a German bunker. They are trapped when the entrances are blocked by the shelling. By coincidence, the bunker is a store house and they have enough food and wine to last them for years. They decide to wait for rescue but eventually realise it's going to be a long wait and they will have to learn how to live with each other in the long term.
