United Six is the story of six girls, living in Bangkok. They are going through a tough phase in their lives. Their dreams have shattered, their aspirations crushed. In this situation, out of frustration and out of anger, they decide to rob a bank. One of the girls, Jia, who was fired from the bank for refusing to sleep with her boss, convinces the others and leads them. They rent a bakery adjacent to the bank and start digging a tunnel which would lead them to the strong room of the bank. They start digging and soon find that it's not as easy as it seemed like. However, they continue in their mission and one by one, on one pretext or the other, the girls start getting jittery. Jia continues to motivate them but finds it getting more and more difficult with every passing hour.
