August 1914, two weeks after the First World War was declared. 80,000 British troops have arrived in southern Belgium, but they have yet to engage the enemy.

Lieutenant Maurice Dease and his friend, Australian Lieutenant Fred Steele, command two companies of riflemen and machine gunners who find themselves camping overnight at Nimy Bridge, the northernmost point of the Mons-Conde canal. The canal, surrounding the town of Mons, supports 18 bridges stretched along 20 miles of water - but everyone, including Private Sid Godley and his mate Private William Holbrook, expects to be crossing those bridges in the morning.
