Riley Keough and Lily Gladstone. The series is based on the true story of the murder of Reena Virk (played by Vritika Gupta), a 14 year old girl who was killed by a group of fellow teenagers – her supposed friends – in 1997 British Columbia. Keough plays Rebecca Godfrey (who wrote the book that the show is based on), Gladstone plays local cop Cam Bentland, and Panjabi plays Suman Virk, Reena’s mother.
