Aftermath (2019)

Aaron is a lone survivor of a mass extinction event. He keeps living his ordinary life in a post-apocalyptic world - tending to his house, going to work, talking to the imaginary manifestation of his dead wife. His comfort and safety is shattered when a homeless bum, in reality another survivor, tries to make him come to terms with his situation. Haunted by the ghosts of his past and his imagination, Aaron will go through a journey of over-coming his denial and rising up to his new reality.
