A decade after defeating the monstrous Kraken, Perseus lives a quiet life as a village fisherman and sole parent to his 10-year-old son, Helius.

Meanwhile, a struggle for supremacy rages between the gods and the Titans. Dangerously weakened by humanity’s lack of devotion, the gods are losing control of the imprisoned Titans and their ferocious leader, Kronos, father of the long-ruling brothers Zeus, Hades and Poseidon.

When Hades, along with Zeus’s godly son, Ares, switch loyalty and make a deal with Kronos to capture Zeus, Perseus cannot ignore his true calling.
