In the year 2022, a ruthless prison warden has created the ultimate solution for his most troublesome and violent inmates: Absolom, a secret jungle island where prisoners are abandoned and left to die. But Marine Captain John Robbins, convicted of murdering a commanding officer, is determined to escape the island in order to reveal the truth behind his murderous actions and clear his name.

During the Boer War, three Australian lieutenants are on trial for shooting Boer prisoners. Though they acted under orders, they are being used as scapegoats by the General Staff, who hopes to distance themselves from the irregular practices of the war. The trial does not progress as smoothly as expected by the General Staff, as the defence puts up a strong fight in the courtroom.
