Mob Sister (Chinese: 阿嫂) is a 2005 Hong Kong action film, directed by Wong Ching-Po and starring Karena Lam, Simon Yam and Eric Tsang.
In the macho triad world where heroes are molded from blood, brawn and brains, what place is there for a defenseless girl? The only exception to the rule is if you earn your respect as 'Ah Sou' - the big boss' wife. Ah Sou tells the extraordinary story of an innocent girl who becomes appointed successor to Hong Kong's ruling triad. This role becomes a double-edged sword for our young heroine, who is sucked into a maelstrom of vicious gang wars, hair-raising assassination attempts and ruthless power struggles and betrayals. Through numerous violent episodes and unexpected reversals, she discovers her own inner strength and re-writes the laws of the triad kingdom.
