Rikuo Sakisaka, who has taken robots for granted for his entire life, one day discovers that Sammy, his home android, has been acting independently and coming and going on her own.

Within the cafe, androids do not display their status rings, and, when patrons depart, the door is automatically locked for two minutes to prevent someone from following them to discover their true nature.

The first few episodes involve conversations between Rikuo (usually accompanied by Masaki) and the cafe regulars: the bubbly Akiko, child Chie and her elderly guardian, the lovers Koji and Rina, and others.
