Three years after being framed as a traitor and presumed dead, former Grey Bay Port Master Cain Vale returns under the identity of mechanic Eli. He discovers that his brother Lucas has turned the harbor into a hub for arms trafficking, silenced witnesses, drugged Cain’s younger brother Nolan, and manipulated Security Commander Cyrus into signing the order that destroyed Cain’s life.
Working with Nolan, hacker Maeve, a frightened doctor, and the guilt-ridden Cyrus—his estranged lover—Cain gathers the weapons ledger, drug evidence, and the original recording that proves Lucas’s crimes. As Lucas launches one final attack against Grey Bay, Cain must choose between revenge and saving the people who once abandoned him.
