Undercurrent (2020)

In a winter evening of 1979, the arrest of anti-government protesters involved in the Formosa Incident is underway. The city is under curfew, but a teenage student, out of curiosity, follows a mysterious young man from a riverside path into an abandoned hut. They exchange their fear and build up a sense of mutual trust there. However, when the student is later caught by a plain-clothes police officer, the young man chooses to turn a blind eye. Living in Taiwan under martial law, are men constantly escaping from the government, the society, or the affection buried in their hearts?
