Due to the growing opposition to elderly people in Japan, the government created a program called "Plan 75." Its goal is to make it easier for seniors aged 75 or older to kick the bucket. Even though it appears harsh and unethical, which it is, Chie Hiyakawa's vision of the future makes it all seem reasonable.
"Plan 75" is about three interconnected stories.
Michi (Baishô Chieko) is already 78 years old. Since losing her job and her apartment, she’s been trying to find a way to keep living. It is not like she can’t work anymore; people are just uninterested in entertaining her because of her age. The pressure of life soon finds her, and at one point it seems like volunteering to sign up for Plan 75 for a small compensation makes sense. She then befriends a young call center agent named Yoko (Yuumi Kawai) who helped her come into terms with her mortality.
A processing agent of the program, Hiromu (Hayato Isomura), has a very interesting encounter during one of his shifts. His widowed uncle Yukio (Takao Taka) signed up for the program for unknown reasons. He’s probably lived a good life and is ready to go, but Hiromu is still curious about it. So he pays him a visit often, and during their times together, he realized one thing: he must convince him not to push through with his decision.
Meanwhile, Filipino nurse Maria (Stefanie Arianne Akashi) is unable to provide for her daughter's surgery. One day, a co-church member offered her a job in the Plan 75 program. The compensation is good, but the work requires medical expertise and a strong heart.
These three characters will eventually cross paths, an encounter will change how one views life and death.
