The film explores the relationship problems of two couples, Kohei and Kinuko, and Manabe and Hijiri, and the solutions they try to devise as a way out. Kohei and Kinuko, despite their age differences, seem like a happy pair, but there is an insurmountable distance between them. Kohei is married to another woman, and Kinuko, though she knows he will never divorce, can't bring herself to break off the relationship and start anew. Manabe and Hijiri, meanwhile, start off happily enough, but eventually their passion begins to wane as Manabe starts looking to other women for sex. Hijiri, feeling rejected, moves into an apartment next door to Kinuko, where she plots to break up the mismatched couple to her own advantage.
