Sundown Road (2020)

The elderly Margie, suffering from episodic but advancing dementia, is cared for in her rural home by Isabel (Bel) and other caregivers. Margie's granddaughter Jenna advises Bel that retaining full-time care has become too difficult, and Margie will be moved this afternoon to a nursing home. Jenna asks Bel to give Margie a pleasant final day by keeping the move a secret. She also warns Bel to prevent Margie from entering a locked bedroom that belonged to Margie's deceased daughter. Margie's last visit to the bedroom triggered a psychotic reaction.
