In Japan, the government's antidote for the huge economic burden of a super-greying population is Plan 75. It encourages citizens aged 75 and over to choose euthanasia as the ultimate right to self-determination in uncertain times. Until now, Michi (78) has lived a modest, self-sufficient life. After losing her longstanding job as a hotel maid, Michi is unable to find new employment due to her age. Her dilapidated apartment is facing redevelopment, but securing new accommodation is a formidable challenge. When a dear friend of Michi meets a miserable end, she's haunted by fears of dying alone. Meanwhile, civil servant Hiromu politely and efficiently signs up seniors to Plan 75 at the local city office. As a strict rule-follower, his work doesn't weigh on his conscience. After a chance encounter with Michi, she finally joins the program, too. However, Hiromu's perspective changes when a long lost family member unexpectedly applies. At the factory-like Plan 75 facility, a young Filipino Christian woman named Maria has the ugly task of processing corpses but perseveres to support her daughter back in Manila. As Michi's scheduled fate nears, these three characters' destinies become intertwined on the brink of life and death.
