Bruce Lee plays Billy Lo, a Hong Kong based movie actor, who is a box office draw. His girlfriend, Ann Morris is a singer who is also climbing to the top. Now it seems the syndicate wants Billy and Ann to join their management firm. But Billy knows that they will be treated like property, so he refuses and tells her to do the same. So they try to encourage his to join but he still refuses. He would be advised that they will not stop, so he must stop them, permanently.
He is even more hesitant to do that but when an attempt on his life is made, he fakes his death and alters his appearance, and decides to go after the syndicate; taking them out one at a time.
