Post It (2017)

The story focuses on Philip, a lonely, elderly man. On his way home one day, he meets Emma and her son, Alfie, who are living across the road. At first, Philip seems like a friendly man, but, as time progresses it is uncertain what his intentions are. Unknowingly to them, Emma and Alfie's day to day life is studied and documented on post-it notes by an obsessive, and increasingly more dangerous, Phillip.
