Agatha (2017) Online
The orphan train comes daily, spilling hundreds of children onto the streets of Pennsylvania in the late 1800's. Desperate and alone, the penniless 7-year-old Sophie, entrusts an older woman who hires her to bring food each night to someone living in her attic. There is just one rule: Do not pass the serving table....EVER." As time passes, the child's curiosity grows bold; drawing her closer to discovering the truth behind the prisoner.
Near the end of the movie, there's a creepy muffled version of the 18th-century French folk song, "Au clair de la lune".
