Instead of telling his wife, Xiao (Jinglei Xu), that he's lost his job, Jian (Le Geng) rides the subway back and forth through Beijing. But problems arise when Xiao interprets his emotional distance as a signal for her to explore a flirtation with one of her clients (Yang Zhang). Meanwhile, Jian plays witness to various romances blossoming around him on the subway. Yibai Zhang directs; Wei Fan and Lan Ke co-star.
