The Heroic Trio (Dung fong saam hap, TC: 東方三俠, pinyin: dōng fāng sān xiá) is a 1993 Hong Kong fantasy adventure film directed by Johnnie To, from a screenplay by Sandy Shaw, and produced by Ching Siu-tung.

A crime fighting vigilante, trained from childhood by her strict martial artist father, she is also the wife of none other than Police Inspector Lau, who eventually finds out who she really is.

Later in the film, Ching's ordered to kill the Professor and take the invisibility suit by the Evil Master, however she is conflicted due to having fallen in love with him, eventually she deciding to fight in his memory after he dies.

An irresponsible and greedy bounty hunter, Chat is initially hired by the Police Chief to rescue his own kidnapped son, stealing a baby from the hospital as bait for the kidnapper.

She grew up and underwent similar training with Ching as a child, though she escaped after three years (taking another ten in order to regain her humanity), being designated originally as "Number 7".

Unlike Tung and Ching, Chat mainly uses modern weapons like firearms and explosives to fight (although she also has a boomerang-like sword) and is an expert motorcyclist as well.

"[1] Variety called the film a "flashy kung fu superheroine adventure full of solid production values but marred by some disturbingly gratuitous plot elements.
