Inconceivable (2017)

Katie appears to be on the run from her abusive husband and trying to simply provide a better life for her daughter when she settles down in a new town. She quickly bonds with young mother Angela Morgan. Angela seems to have the perfect life, and she's happy to welcome Katie into her home as a nanny and as a friend. But as Katie becomes increasingly obsessed with Angela's family — and with her daughter in particular — Angela has to wonder whether she could actually be a threat. Katie has plans to tear the family apart, and she's more clever than she might initially appear.
