The Karpov Bridge is the last artery out of the besieged city of Dnipro, and Captain Viktor Radek, a commander haunted by past failures, has just been given an impossible order: hold it at all costs. His command is a fractured collection of survivors: a disillusioned American ex-Marine with a history of mistrusting command , a guilt-ridden Polish medic who has already lost everything in the war , and a street-smart teenage artist whose graffiti reveals more than military intelligence. Their mission is compromised before it even begins when the explosives wired to the bridge are expertly sabotaged , and Viktor realizes the enemy isn't just on the other side of the river—there is a traitor in their midst.

As suspicion and paranoia threaten to tear the fragile unit apart , a quiet communications officer, Anton Yermak, masterfully frames a tragic schoolteacher to mask his own betrayals. With Russian tanks hours away and the true mole still operating in the shadows, Viktor’s small band of defenders must uncover the conspiracy while facing an impossible choice: destroy the bridge to save the country and sacrifice themselves, or save themselves and let the nation fall. At the last bridge at Dnipro, the only thing more dangerous than the enemy you can see is the one standing right beside you.
