On a long overdue vacation, Maj. Andreas Vassos takes his family from Athens to a resort village on the Grecian coast, hoping for sun, surf, and a few days without worry. It's just the holiday he needs—until the family goes to get a treat and the crowded café is raked with gunfire. Acting on instinct, Vassos grabs a pistol from a murdered cop and chases after the killers. He's able to take one down, but the other escapes. The hunt is on. The deaths are tied to the search for a priceless Greek artifact. And finding the killers and saving the relic takes Vassos to New York City, where he forms a partnership with the NYPD's Teddy Lucas, a Greek immigrant once known as Theodorous Loucopolous. They may not speak the same language, but cops are cops, and either of these men would lay down his life to save his brother in blue.
