After the war with the Kraken, the hero Perseus (Sam Worthington) and his son Helios (John Bell) live a quiet life in a small village. But the war in Olympia never stops. The gods, led by Zeus (Liam Neeson), are engaged in a protracted and brutal war with the Titans. Even Kronos, the father of the three gods (Zeus, Poseidon, Hades), who has been imprisoned by Zeus for a long time, is about to be resurrected. The balance of war gradually tilts towards the Titans. Under the planning of Hades (Ralph Fiennes), Zeus mistakenly enters the underworld, loses all his power, and is imprisoned. In order to drive away the darkness and bring light back to the earth, Perseus puts on his armor again and goes to the underworld with a group of heroes to rescue Zeus. The war of the gods has reached its most critical moment... This film is the sequel to the 2010 3D movie "Clash of the Titans".
