THE FLORIDA PROJECT focuses on a trio of young, largely unsupervised kids whose families live in cheap motels just minutes away from Walt Disney World, outside Orlando. Six-year-old Moonee (Brooklynn Prince) is a resident of the Magic Castle Motel, a purple, bed-bug-infested place that would love to cater to tourists but actually attracts unemployed or working-class folks who can’t afford security deposits. For $38 a night, Moonee and her young, laid-back mom, Halley (Bria Vinaite), live there for all but one night each month (the one-night-off rule prevents them from establishing residency and triggering tenants’ rights). Moonee spends her school-free summer days roaming around Kissimmee, Fla., with her downstairs neighbor, Scooty (Christopher Rivera), whose mom, Ashley (Mela Murder), is a diner waitress who hooks Moonee and Halley up with daily bags of food in exchange for babysitting. Scooty and Moonee also hang out with Jancey (Valeria Cotto), a girl who lives with her young grandma in the motel next door. Presiding over the Magic Castle is its stoic manager, Bobby (Willem Dafoe), who finds himself serving as a reluctant father figure to his motley crew of guest residents.
