The Killgrin

The Killgrin (2025) is a Canadian horror you can watch online on iFILM. Director Joanna Tsanis casts Konstantina Mantelos as Miranda, a woman trying to piece herself back together after a serious loss. Support groups do nothing for her. She ends up at a spiritual healer instead.

The healer delivers bad news: Miranda has a killgrin — an aura parasite that feeds on misery and grows more dangerous the worse she feels. When her pain gets bad enough, the entity targets the people around her. It leaves a signature: a wide, frozen smile on every face it touches. The concept works because grief becomes the vector of harm — the harder Miranda tries to cope, the more danger she creates for others. Stream The Killgrin (2025) online on iFILM.
