Loosely based on the Greek myth of the Argonauts, Argo focuses on its central protagonist Iason (Jason), narrating a simple story that does not quite correspond to the known myth: Iason's father has been poisoned, and his native city Iolkos overrun by monsters known as Pontos. Iason must single-handedly eliminate them and save his homeland.
