A day of kayaking on the East River turns tragic when Conrad Voort and his fiancée, Camilla, find a corpse floating in the water at Hell"s Gate, a ship graveyard dating back to colonial times. The discovery seems at first tied to the accident-strewn history of the treacherous passage, but Voort begins to suspect a more modern and global enemy is emerging and when he begins to ask questions he himself is targeted. A man with the power to destroy all that Voort holds dear stages an unimaginable attack that leaves the detective broken and on the run. Defying the laws of his extended cop family and of his brother officers, he returns to exact revenge -- alone.
