It stars Gayle Rankin, Hari Nef, Annabelle Dexter-Jones, Jared Abrahamson and Molly Ringwald.
Ruthie has recently inherited her grandmother's abandoned hotel, and has returned to stay in it for a few days with her girlfriend Cal, their friend Maddie, and tagalong Fran.
The groundskeeper, Brian, arrives, expressing his disappointment that Ruthie's estranged mother, who had been staying at the hotel, has ended things between them before leaving town.
Cal and Maddie, noticing Ruthie's gradual mental decline, are wary when she insists that Fran has returned and is a murderer.
Ruthie breaks back in, discovering to her surprise the buyers there to discuss their terms, along with Ms. Auerbach, who claims she is a consultant.
Maddie and Cal flee the hotel grounds, but Ruthie chases them down with the chainsaw, murdering them in a strip mall parking lot while pedestrians walk by without reacting.
When creating the film, writer and director Stewart Thorndike wanted to feature a predominantly female and LGBTQ cast, as she felt that these groups were not properly represented in horror and thriller cinema.
[1] Gayle Rankin was brought on to play one of the film's central characters, Ruthie, while Hari Nef was confirmed as portraying Cal.
