The four brave men once again traveled back to the dangerous game world to start a new adventure. Unlike the last time, it was Spencer's grandfather who transformed into Dr. Brave Stone (played by Dwayne Johnson), and his grandfather's friend transformed into a linguist (played by Kevin Hart). The tall and mighty Fridge became a middle-aged fat geologist (played by Jack Black). Only the top student Martha still transformed into a sexy fighting girl (played by Karen Gillan), while Spencer and Bethany were missing. In order to rescue the missing partner, the four must enter an unknown world that is completely out of control. Faced with the deadly levels with extremely difficult and dangerous levels, Johnson led the team to challenge the limit and fight to the death. In the dangerous situation of landslides and cracks, their lives are hanging by a thread, and they have to fight to the death with the sudden ferocious beasts. Only by tensing their nerves and fighting side by side can they pass the test of life and death and escape. A thrilling and surprising adventure is about to begin!
