The epic battle between the Titans and the gods continues in this sequel set ten years after the events in Clash of the Titans, as Perseus Sam Worthington descends into the underworld on a mission to rescue Zeus from the clutches of Hades Ralph Fiennes, Ares Edgar Ramirez, and Kronos. In the wake of his decisive victory against the Kraken, Perseus has retreated to a remote fishing village to raise his young son, Helius. Meanwhile, humanity has lost faith in the gods. As a result, Zeus, Hades, and Poseidon find their power beginning to slip, a development that could spell disaster for all of humankind should their imprisoned father, Kronos, manage to break free from his underworld prison in Tartarus. When Perseus learns that Zeus' son Ares has teamed with Hades and Kronos to capture Zeus, steal his power, and create hell on earth, the time comes to take action. Now, with Andromeda Rosamund Pike, Argenor Toby Kebbell, and Hephaestus Bill Nighy by his side, brave Perseus will venture deep into the underworld on a mission to defeat the Titans, deliver Zeus from evil, and prevent the powers of darkness from consuming all of humanity.
