Set about ten years after the events of Clash of the Titans, Wrath picks up with demigod Perseus (Sam Worthington), having shunned his demigod status and choosing to live a normal life, working as a fisherman and raising his son, Helius. There isn’t much mention of Io, his wife, aside from the fact that she died, but Perseus trudges on trying to raise his son away from the shadow of the gods.
Perseus gets a visit from his father Zeus (Liam Neeson), who tells him that because mortals have stopped praying to the gods, they’re losing their power. The lack of belief is creating a chain reaction, which results in the weakening of Tartarus, the underground / underworld prison where the gods sent the titans. It’s kind of like Azkaban, but without the Dementors. Anyway, Zeus asks for Persues’ help, which he refuses. Shortly after, Zeus is captured by his brother Hades (Ralph Fiennes), and his other son, Ares (Edgar Ramirez) so that they can transfer Zeus’ power to resurrect Kronos, father to Zeus, Hades and Poseidon. With me so far?
