Unable to bear the cruel oppression of the Olympian gods, Argos King Argos (Jason Flemyng) rose up in rebellion and was greatly disrespectful to the supreme gods. Under the instigation of Hades (Ralph Fiennes), the god Zeus (Liam Neeson) decided to punish stupid humans. Perseus (Sam Worthington), a young man who was stranded in Argos after a shipwreck, was a demigod born to Zeus and the queen of Argos. He witnessed the terrible miracles performed by Hades with his own eyes, and learned that Hades would release the North Sea monster Kraken to punish the world, unless Argos sacrificed the beautiful princess Andromeda (Alexa Davalos) to the gods. Under the guidance of the goddess Io (Gemma Arterton), Perseus knew his life experience and mission, so he decided to set out to kill the North Sea monster and destroy Hades' conspiracy... This film is adapted from Greek mythology and legends, and is also a remake of the 1980s film of the same name.
