Gong Li, the female icon of modern Chinese cinema, teams up with Sun Zhou, following their collaboration on the moving, and award-winning, drama "Breaking The Silence". She gives a stupendous performance in possibly the most sensual role of her career, as a woman caught between two lovers, and two dimensions of desire.

Zhou Yu, a ceramic artisan in China's rural northwest, has a deep rapport with Chen Qing, a shy, sensitive poet. Taking a long train ride every weekend just to make mad passionate love with him, her longing seems insatiable. Until one day, she meets the hedonistic vet Zhang Qiang, and begins a torrid affair which takes her to another train station, and another level of lust.

Driven by the locomotive of love and desire, she hurtles through a dark tunnel of no return.
