The Cure (2021)

Harper isn't feeling too good. Her friends, Katya and Larisa, come to look after her. What they don't realise is that they can help her get well, in a way they never expected. Flatmate Lucas also adds to this mysterious cure. One by one her friends disappear, providing just enough assistance to get her well again. Then when the final visitor for the evening turns up, feeling a little under the weather herself, the tables are turned.
