A Dark Beginning: In 2003, Adil Rahman, a young Pakistani American, is kidnapped by the U.S. military in the name of counterterrorism and taken to Guantanamo Bay. After enduring inhumane abuse, he becomes Prisoner No. 715, beginning a nightmarish life in captivity.
The Truth About Torture: Colonel Richard Hayes, the prison warden, establishes a secret "Zone X" to carry out torture. Former military medic Mark Williams discovers the atrocities and begins secretly documenting them, but faces a difficult choice between conscience and loyalty.
The Fire of Resistance: In prison, Adil meets Hakim, a former member of Al-Qaeda. The two go from hostility to cooperation, scheming to exploit gaps in prison security to pass out evidence of the abuse within.
Crisis and Opportunity: When Mark's notebook is discovered and triggers a massive prison search, Adil risks everything to hide the evidence in a homemade message bottle and cast it into the sea, leaving one last hope of exposing the truth.
Fates Intertwined: As Adil faces a mental breakdown after being placed in long-term solitary confinement, Mark decides to desert the military, vowing to reveal the dark truth about Guantanamo Bay to the world.
