Synopsis

Three betrayed wives form an alliance to exact revenge on their cheating husbands.
 
Natsuko is a housewife whose spirit has been worn down by life with her husband Yoshitaka, who turned emotionally abusive after their marriage. One day, she comes home to find him in the act after bringing his affair partner into their home. Unable to bear it, she flees — only to receive an unexpected message from Yoshino, a friend from her college days…
When they meet up, college classmate Saotome Reina is also there, and it quickly becomes clear that all three women share the same betrayal: a cheating husband. Together, they form a revenge alliance, vowing to carry out a “swap revenge” on each other’s husbands.
