Rick O’Connell is an explorer who is enjoying some well-earned relaxation time with his wife and fellow explorer Evelyn. It is 1946, and the two explorers are starting to get bored with their rest. When the British government asks them to return a priceless diamond to China, they both are happy to get a little excitement back in their lives. Known as “The Eye of Shangri-La,” this precious gem has a hidden power. It can bring back to life the evil ancient Chinese Emperor Han and his army of undead soldiers. A Chinese general steals the diamond from the O’Connell’s and brings Emperor Han back to life. Now, the O’Connell’s must team up with their son, who they have found on an archeological dig in China, to get the diamond back and put a stop to Emperor Han.
