When three rebellious students leave their hometown to pursue their lifelong dreams in the big city, their relationships start to face the pressures of real life as the 1980s Taiwanese sociopolitical reformation movement unfolds in the background.
Told over the span of 30 years, the movie begins with a brief prologue set in the present day before it goes back in time, where we are introduced to three Taiwan high-schoolers: Mabel (Lun-Mei Kwei from "Black Coal Thin Ice", "Taipei Exchange", "Parking"), Liam (Hsiao-chuan Chang from "Soul", "Eternal Summer") and Aaron (Rhydian Vaughan). Longtime friends, Mabel, Liam and Aaron were born in the same small town, deep in the far south of Taiwan. All of them are activists rebelling against the martial law during the turbulent period of Taiwan's social revolution. Later, as students in Taipei, they fight even harder for their ideals whilst riding the tide of Taiwan's immense social change.
Now adults in this final, hotbed year, new feelings arise between the trio that will alter the childhood bonds between them forever: Mabel loves Liam a lot, but Liam doesn't really have a feeling for her. So she ends up falling in love with Aaron instead. In fact Liam is a closeted gay who's been longing for Aaron. In the course of this, long held secrets are revealed. Coming almost full-circle, the old friends who are there for one another through times of emotional hardship and extreme tragedy come to realize the true value of their lifelong friendship. It's a well-made, coming-of-age drama that explores friendship, romance, sexuality and politics.
