Chongqing Hot Pot 2016

Three high school classmates open a hotpot restaurant in an old bomb shelter in Chongqing. The business turns out a glorious failure. They find a buyer for the restaurant, but must first "enlarge the space." Digging, they emerge in the vault of the bank next doors.

Now they must devise a plan to sneak into the bank and fix the hole. Lucky break: a girl they know from high school is working in the bank. Bad break: the bank is a target of some badass robbers.
