A martial artist stops a street gang from stealing her car, but her grandmother ends up being killed by the same gang. She witnesses firsthand how corrupt and inept law enforcement is, and decides to take matters into her own hands.

Somewhere in the seedy side of 1980s Los Angeles, Billie, a feisty black-belt karate expert, finds herself in the crosshairs of the local gangster, Scarface. After the brutal assault of her grandparents, Billie embarks on a mission to rid the neighbourhood of Scarface and his thugs, eager to serve a hearty slice of good, old-fashioned vigilante justice. Now, there is no turning back, and as Billie catches the attention of corrupt police officers and the sluggish penal system, she decides to take matters into her own hands. Who dares to get in the way of the dangerous alley cat?—Nick Riganas
