Liu Xing (Liu Ye), a physics graduate student, went to a state university in the United States for further studies. During his time at the university, he studied under the famous professor Jacob Reiser (Aidan Quinn). His diligence and outstanding talent quickly made him stand out among his peers and won the trust and appreciation of Professor Reiser. Among many topics, Liu Xing was fascinated by dark matter. He devoted himself to this research, but he did not expect that the theory he obtained would conflict with his mentor's classic Reiser model. Liu Xing's paper on dark matter won a lot of praise, but he was so absorbed in his research that he ignored the existence of campus politics and his defense was not passed. In extreme depression and indignation, he embarked on a path of no return... This film is adapted from the Lu Gang incident and won the Alfred Sloan Award at the 2007 Sundance Film Festival and the Best Feature Film Award at the 2007 Asian American Film Festival.
