Work From Home (1970)

In the not-so-distant future, all Australians work from home. They strap into their Sensory and Communication Masks (ScoMo) and peddle all day long, ignoring their overheating world outside. All but one. Mags is a janitor. She goes from home-to-home fixing, cleaning, and feeding the workers who are unaware of her presence. Her only company is her taxidermied dog, Malvern. But one day, Mags finds one of the workers dead on the job and her entire world begins to collapse.
