The Pharaohs (2018)

A clique of "mean girls" in an upscale nursing home call themselves 'The Pharaohs.' When one of their members becomes infirm and cannot feed herself, the Pharaohs expel her. She feigns happiness to be excluded, but eventually tries to rejoin the group. When she is rebuffed, she resorts to violence and ultimately finds herself in a living arrangement she would never have imagined.
