Lost City Raiders

When rising sea levels swallow up cities across the globe, treasure hunting brothers Jack (Ian Somerhalder) and Thomas (Jamie Thomas King) follow their father (James Brolin) on a quest to seek out a powerful ancient artifact capable of restoring the balance between the sea and the earth. When the daring adventurers discover that a malevolent real estate tycoon (Ben Cross) wants to use the artifact to rule the planet, they find themselves in a frantic race to ensure that its powers are used for good rather than evil.
