Grace Waters was accused of killing her husband, but her lawyer helped her. It turns out the younger man Grace married was the son of her friend, Sarah. It has been their long-time scam; both mother and son victimize older lonely women and have money. Grace was released from prison, and the other women hidden in Sarah’s basement were also released. Sarah’s son was killed (the lawyer, Jasmine, killed him while trying to escape). Sarah was able to run, and she managed to find another victim.
