Mojin: The Lost Legend (2015)

In 1988, the three Mojin(tomb raider), Hu Bayi, Wang Kaixuan, and Shirley Yang, retires and relocates to New York. While Bayi and Shirley have become romantically involved and Kaixuan feels that the great Mojin deserve more than the financial despair they've faced in the States, the trio are pulled back into a grave-robbing game in Inner Mongolia, China, to explore the reason behind the death of Ding Sitian, who was Bayi and Kaixuan's first love died back in 1969.
