Plot: On the first day of year one, all Japanese students receive an inoculation. A small percentage of these inoculations includes a nano capsule which via radio-control will kill the receiver somewhere between the ages of 18-24. The government believes that the threat of unexpected death will increase prosperity and productivity in its citizens. And indeed this increased prosperity is evident, but at a great cost, innocent lives. Citizens who do not agree with the National prosperity law and who publicly voice their opinions are accused of "thought crime."
Kengo Fujimoto (Shota Matsuda) has been recruited by the government as an Ikigami delivery man. Whilst undergoing training he witnesses the "arrest" of a man (also undergoing training to become a deliverer) who commits a thought-crime when he yells to the entire room that the law is wrong and that his girlfriend died from the ikigami. The Film follows Kengo as he delivers Ikigami too 3 citizens: a rising musician (Yuta Kanai) debutting in the music industry but struggling with leaving his friend behind as a busker, a shut-in (Kazuma Sano) who is the son of a council woman (Jun Fubuki) who supports the law whole heartedly and attempts to use her son's upcoming death to gain sympathy votes, and a working class debt collector (Takayuki Yamada) who is about to take his blind sister (Riko Narumi) out of the orphanage she lives in now that he is finally financially secure.
