Based on real life war diaries, Before Dawn is an epic retelling of one of Australia’s biggest military victories during World War I. Jim Collins (Levi Miller), a young man from the outback, leaves his family-run sheep station to join the soldiers on the western front with hopes of making a difference. But soon, the realities of the muddy, ruthless, and entirely unforgiving war take their toll on a guilt-ridden Jim.

As the men in the battalion are whittled away and hope becomes a distant memory, a final chance at redemption arises amid one of Australia’s greatest battles. Jim must risk death, or forever carry the burden of leaving yet another man behind.
