Disgraced Marine Raider Ryan McGowan is running out of time. Haunted by failure and battling the slow burn of depression, he needs one last shot at purpose--before it kills him.

When shadowy private military contractor Mike Hudson offers a high-risk job in the South Atlantic, Ryan jumps at the chance. The mission: lead a crew of battle-hardened, disgruntled operators to police Argentina's territorial waters and stop a massive fleet of Chinese fishing vessels that are causing billions in ecological and economic damage.

What begins as a straightforward maritime security detail quickly explodes into a brutal, no-holds-barred fight on the high seas. Outnumbered and outgunned, Ryan and his team must use every dirty trick from their special ops past to confront the ruthless fishing armada and the powerful interests protecting it.

Part military thriller and part neo-western, Once Upon A Time in Argentina delivers old-school, blood-soaked action with dark humor and unflinching grit.

For fans of Jack Carr, Mark Greaney's Gray Man series, and Taylor Sheridan's hard-edged storytelling--this is a high-octane ride you won't want to miss.
