Of the many titles given for this movie, I viewed the movie as titled "The Daughter Stalker." When "long lost sister" Nikki dies, she stipulates in her will that sister Carly inherit her house and raise her young daughter Zoey - who stands to inherit her mom's fortune. Meanwhile, Nikki's husband Corey and stepfather to Zoey is none to happy about any of it.
The movie relies on a series of plot contrivances and conveniences to get to this point - namely, how many long lost sisters are in a position to drop out from their current job or life entirely and run a flower shop, raise a tweener, and relocate to another city altogether.
We initially never get a clear explanation how young fit Nikki died out on a wilderness trail and APPARENTLY no one bothered to do an autopsy (which would have revealed a poison) or do a cursory examination of her phone (which would have revealed hints of an affair) - despite the fact that her and her husband were known to be having very public spats.
And I guess when an elderly woman is found dead on her house, I guess the medical examiner presumes they died of their known health conditions. Case closed.
Then, curiously, when the toxicology comes back on Nikki that she was poisoned, the first person the medical examiner calls is her husband - whom we would presume is then a potential suspect - and not the authorities.
All those things aside, this is still a decent whodunit with the usual convoluted revelation of the perpetrator's motives.
So I would rate this as better than average.
