The battalion heads for Europe. The soldiers spend weeks at sea in bunks stacked five high, and none of them believes that Ken is from the future.

Meanwhile, Ken remembers his childhood with his grandfather – a man whose uniform he is now wearing.

This series is inspired by real events and contains dramatised battle scenes and out-dated racial language.
