Detectives in Greece struggle to solve multiple murders - and confront a shadowy group claiming that the goddess Athena is behind the carnage . . . After an unidentified body is found at the Temple of Hephaestus, arranged to resemble the myth of Athena's birth, officers Michail Mikras and Katerina Galanis are assigned to the case, led by a senior detective recently transferred from London. Amid growing media coverage, a group calling itself The Awakening puts out ominous social media posts, claiming that this crime proves the goddess Athena has returned to "cleanse" the city of Athens. With each new corpse, the mania grows - chants of "Athena is arisen" ring out; a rabble-rousing newspaper suggests that the goddess is purifying the city by getting rid of immigrants; graffiti of axes and snakes start to appear. As raucous rallies spring up throughout the city, the team of investigators must solve the case to break the spell before an unimaginable horror comes to pass . . .
