The Last Tour (2016)

Jun Lee (Ryun Yu), dishonorably discharged from the Army, cannot keep his family fed and accepts a seedy mercenary job: Kidnap a rich guy, Paul (Jeff Liu) and convince him that they've taken him to North Korea, all the while keeping him in a hotel somewhere in the desert. Jun has an acute attack of conscience, and frees Paul, which he quickly regrets, when he learns the real reason that Paul is there. Soon the mercenaries are after them, and the stakes are revealed to be unexpectedly high. Jun turns for help to his survivalist Aunt (Diana Lee Inosanto) and Uncle (Ron Balicki) , who live out in an inaccessible canyon in the deep desert - and soon the motley crew must find a way to fight off the heavily armed professionals.
