I've just done some basic copy-editing:
Former New York detective JORDAN ST. JAMES quits her job after accidently killing a little girl during a shootout. She and her sister leave New York and move to a small town in California, hoping to start fresh. Not ready to go back to work, Jordan uses her investigative skills and resources to help her fellow townies. When one of her neighbors asks her to find her son’s missing dog, she agrees. Believing it to be a simple case, she convinces her younger sister ERIN, an unemployed third grade teacher, to help.
While searching for the dog, they find a fresh grave and, believing it contains the dog, dig it up. Instead of the dog, however, they find two bodies. The medical examiner’s report on the bodies shows that some of their organs had been removed. Jordan and Erinfind the dog nearby,muzzled and tied to a tree. The cruel treatment of the dog angers the sisters, and they vow to find the person behind it. Their search leads them to JONAH FRANKLIN, one of the town’s doctors, whose wife was in a three car collision. The crash resulted in severe damage to some of her organs.
When Dr. Franklin and his accomplices realize that Jordan and Erin are getting close, they send someone to slow down their investigation. One night as she's on her way home, Erin is attacked by a knife-wielding man wearing a mask and hoodie. For the first time she puts to use the fighting skills her sister taught her and saves herself. The attack enrages both Jordan and Erin, making them even more determined to get the evidence needed to put the perpetrators behind bars.
Not only do the sisters find evidence linking the doctor and his accomplices to the dog, but they also find evidence connecting them to the disappearance of a number of indigent people from Los Angeles whose organs they’ve been harvesting.
Finding appropriate organs is taking much longer than Franklin expected, because so many of the ones he's already stolen are unhealthy.
When the sisters spy two of the doctors carrying a woman into Franklin's house, they break in to rescue her. They find her in the basement along with jail cells, operating rooms, and bags of blood stored in a meat locker. Jordan takes pictures of everything with her cell phone and sends them to her former partner and ex-lover detective AMANDA POSEY in the Sheriff’s department.
Soon one of the doctor’s accomplices comes down to the basement with the intention of putting an end to the sisters and their investigation. Using her martial arts skills, Jordan knocks him out and useshis keys to lock him up in one of the cells.
They make their way back upstairs where they send the photos.
The police arrive and search the house. They find the doctor’s wife hooked up to machines. After subduing the doctor, they place him under arrest. The sisters join forces with detectives to find one of the suspects who has escaped. When they catch up to him, Jordan and Amanda take him down.
Later Jordan and Erin track down a fourth accomplice and finally, after a year, the case is put to rest.
