Mollies and Moxie

It's the wrong side of the tracks and teens and young adults do what they can to make their way through life.
Moxie had her own troubled childhood, taking care of her younger sister, Harley. With their mother too doped up and drunk, she had to play mommy while getting herself through school and now work.
Cale and Natalie, a brother and sister duo had it hard growing up in and out of foster care, having minimal contact with each other. Now in his late twenties, Cale has custody of Natalie who is finishing off high school by just skating by.
Chase and Tess are siblings but they live on the better side of town, where they run the drug ring that roped the other three in, among others willing to sell their souls and dirty their names.
One morning, someone is found dead and everyone isn't so sure it was accidental. With everyone pointing fingers at everyone but themselves, who did it?
