She Shoots Straight (1990) [Blu-ray]

Inspector Mina is a career-focused officer who has just married her supervisor (Tony Leung Ka-fai), who himself comes from a family of dedicated police officers. Her new sisters-in-law are a little jealous that Mina outranks them, but when a gang of violent Vietnamese criminals (led by the always excellent Yuen Wah) target the family, the sisters unite into a lethal force of vengeance.
