As of the end of 2015, there are almost fifty thousand illegal migrant workers in Taiwan and most of them are from Vietnam. The director of the film is a newly immigrated Vietnamese-Taiwanese who happens to know some of these Vietnamese workers living outside of their own country. With careful observations and many small conversations, she gradually understands this group of distant but familiar friends and their reasons for embarking on this money-making journey full of frustration, fear, and hardships.
