Kristi Jones, a member of a local street-gang, waits on tables so she can send her younger sister, Karen, through college and then medical school. When funds are short, she returns to what she knows best - street fighting. But when Karen is found murdered, Kristi is determined to avenge her death, venturing into seedy corners of the city and battling rival gang members and street fighters to seek out her sister's killer.
