On the wrong side of the grass

The Norths are a happy family living in Los Angeles, the City of Angels. Until one day the father Chris and daughter Carly are murdered. Drive-by shooting. Gang-style. Ludicrously everyone in the city - including the judge and the prosecutor - are afraid of gangs, so there's no conviction of the death of Chris and sweet little Carly! It's preposterous! They even have the nerve the send the bereaving widow into a mental treatment program, the psycho ward! Luckily, Riley North has other ideas. She wants to avenge the death of her family. Shit for brains.
