As dawn breaks on April 25, 1915, ANZAC troops go into battle on the beaches of the Gallipoli peninsula. Landing in the dark chaos, Tolly, Bevan and their mates struggle to establish a tenuous foothold on the treacherous slopes and deep ravines. They endure the next eight months on the peninsula learning lessons of survival. By the time of the final evacuation they have also learned the skills of combat and what it means to be a young man in war.

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. Journalist Ashmead-Bartlett visits Lord Kitchener in London with dire reports on the Anzac campaign.
