His manager hires Dan to protect him but he feels that his manager is overreacting. And Dan doesn't want to work for someone as obnoxious and inconsiderate as him and was about to quit when some men beat him up. Dan decides to look into it further and discovers that his girlfriend is involved with the man behind everything. When they try to get her he lets her go away. Later, his sister is kidnapped and he agrees to throw the match. Dan deduces that either the manager or the promoter is connected to the man, so when he goes to his office to find the sister, he subdues the man and his henchmen and discovers that it's the promoter. He finds the sister and arrives just in time to let her brother come from behind.
