The Florida Project

During the summer, six-year-old Moonee lives with her young mother Halley in the Magic Castle, a motel in Kissimmee, Florida. She spends most of her day unsupervised with her motel-resident friends Scooty and Dicky, engaging in mischief at other motels, mooching from tourists at nearby businesses, and other misbehavior. They invite Jancey, a new child living at the Futureland motel next-door, to hang out with them. Following an incident, Dicky's father restricts him from hanging out with them, and the family eventually relocates to New Orleans, which upsets the group. Read more on Wikipedia.
