At dawn on 25 April, 1915, four mates land with the Anzac troops at Gallipoli and find themselves in a chaotic and heroic battle for the Turkish heights.

After a month of heavy fighting, the Anzac and Turkish soldiers meet in No Man's Land during a cease fire to bury their dead. Tolly risks his life by charging a machine gun nest to protect his brother.

Tolly is promoted ahead of his older brother, but disaster strikes when their platoon launches a surprise midnight attack.

Tolly recovers from his injuries in Cairo, then reluctantly returns to the front line at Gallipoli, where he volunteers for sniper duty.

In August, General Hamilton coordinates a complicated series of feints and attacks in a final push to take the Gallipoli peninsula.

The aftermath of the failed breakout is felt and General Hamilton requests more troops while many of his officers dissent. Bartlett sends a letter to the British Prime Minister via the Australian reporter Murdoch.
