Sayaka Mikimoto, a 37-year-old housewife from Chiba Prefecture, has been married for 12 years and is a busy mother of one.

Feeling neglected and craving attention, Sayaka admits, "I'm bored, I'd like to have sex every day," and turns to a dating app on her smartphone to find someone new. This is a raw, shocking documentary capturing the real emotions and circumstances of a married woman on the edge.
