　　在一场残酷的地下锦标赛中，世界顶尖刺客展开殊死搏斗。然而，他们之中却隐藏着一个叛逆的团伙，他们怀揣着自己的致命阴谋：潜入比赛现场，在血腥屠杀中幸存下来，并扳倒幕后主谋。

　　They Might be Giants chronicles the adventures of Sherlock Holmes and Dr. Watson in modern-day New York City. The fact that Sherlock Holmes is a psychotic paranoid and Dr. Watson is a female psychiatrist fascinated by his case is almost beside the point.

This is a sweet, goofy and fairly romantic film that asks the questions "Whose reality is right...and does it really matter?"
