Two newly demobilized marines Fyodor Chaika and Lekha Larin go sea fishing in the Black Sea. Friends are caught in a strong storm that takes them far from the shore. Having escaped, they discover that they have “failed” in time. The year is 219 BC. One year before the start of the Second Punic War. The most ambitious war for the future of the ancient world between the superpower of Carthage and the young Roman predator. Finding themselves in the thick of things, friends take a direct part in the war, before which even the siege of Troy pales. Not only the fate of the states along the shores of the Mediterranean Sea, but also the fate of the entire unborn world will depend on the outcome of this battle.
