In Memorium (2005)
Two months after being diagnosed with terminal cancer, Dennis Wade, a struggling filmmaker, decides to document his illness. Still free from symptoms, he and his girlfriend, Lily, sublet a house and install motion-triggered security cameras throughout. Two days later…the cameras capture something unsettling: Noises and movement in empty rooms. The next morning, Dennis’ cancer begins to advance at an inexplicable rate. As Dennis worsens by the day, he and Lily discover the horrific source of the disturbances. With his time running out, they must make a decision: Leave the house and save her life…or stay…and save his.
