Tianhuo Island is a beautiful paradise. It almost makes people forget that it is located in the 'Ring of Fire', the world-famous Pacific Rim volcanic belt. A brand-new resort opens to the public, owned by Jack Harris (Jason Isaacs), next to a stunning mountain range & a dormant volcano, that his company runs day trips into the heart of. It’s the most idyllic place on earth, until the mountain decides to wake up!
