På palmblad och rosor (1976) IMDb
Seen in 2019.
One Saturday morning, a man delivers a TV extension cable to a cabin in the woods off a lumber road. To his surprise, the place is empty except for a little old lady, awake on her bed but completely senile and unresponsive to his presence. He becomes obsessed with her as a symbol of lost freedom: The freedom to fade away without anyone knowing. To die without bureaucracy.
Nicely understated, but the sexual relationship between Proppen and Gabriella is distractingly implausible, as is the ending.
