Gray Matter
A group of locals at a liquor store brave a winter storm to check on Richie (Larry Fessenden) a regular customer who hasn't left his house in months and - according to his terrified son - has been slowly "changing shape". What waits for them inside the house, in the dark, is beyond their wildest nightmares.
