The film stars Wu Kang-jen, Aviis Zhong and Yu Tai-yan.

Unknown to anyone else, the socially inept Bai has an uncontrollable fetish for women's underwear due to a traumatic past event.

One day, he receives a video recording of himself caught in the act of stealing female lingerie, leading to a gradually accumulating sense of anxiety and fear of exposure with tragic consequences.

Elizabeth Kerr of The Hollywood Reporter stated, "Carefully modulated and wisely attuned to its strongest elements, White Ant is evidence of Chu's doc background, both in style and substance."

She concluded that the film is "a strong exploration of the psychological impact of shame, fear and guilt".
