The Sensei (2008) is an independent feature film, written, produced and directed by Diana Lee Inosanto (credited as D. Lee Inosanto).
Set in Colorado, the story takes place in 1985 during the rise of the AIDS panic. McClain Evans is a gay high school student, constantly the target of bullying in his town. Karen O'Neil is a woman haunted by the death of her pro-boxer fiance, Mark Corey. After a five-year absence, she returns to her family, who runs a successful martial arts school. When McClain is attacked by three local teens, his mother, Annie, asks Karen to teach her son martial arts so that he can defend himself. Karen's family is fearful of anti-gay retaliation, so Karen is forced to secretly teach McClain at night. When word of this reaches her family, and the small-town community, violence erupts, and family and friendship are challenged, forcing Karen to reveal her own dark and tragic secret to those she loves most.
