Emelie (2016)

After their regular babysitter Maggie can�t make it, the Thompson family turns to her friend Anna to supervise their children while the parents go out to celebrate their anniversary. At first Anna seems like a dream come true to the kids, allowing them to eat extra cookies and play with things that are usually off-limits, but as her behavior becomes increasingly odd, the kids soon find out that her intentions are dark and twisted, and she is not who she seems to be.
