It is the sequel to Black Scorpion (1995), and stars Joan Severance, reprising her role as the titular crime-fighting superhero.

The Black Scorpion does not have any super powers but, like Batman, she fights for justice using a combination of martial arts and advanced technology, including her high-tech car, the Scorpionmobile.

When a series of earthquakes shake up the major metropolitan area, seismologist Prof. Undershaft had pioneered groundbreaking technology made to prevent such disasters in the future.

But the duplicitous and corrupt Mayor Worth had her life's work sabotaged in order to embezzle tremor insurance, and assigned blame for the fault device ruining the city on her.

Now Black Scorpion must protect the city from the vindictive Undershaft, who has become the lethal supervillain femme fatale Aftershock.
