On a sunny summer morning, a day before the wedding, the groom's parents visit the bride's parents. They all quickly discover that it is not their spouses who are their soul mates. As a result of the meeting, the couples reshuffle and two new relationships are formed. They start to drift away from each other, especially after their children's text message saying that the wedding is called off, as the bride and groom got in an argument and broke up. One of the couples starts behaving as if it took over the bride and groom's place. They practice their dance, taste wedding dishes, and finally, begin to interfere with the wedding decoration. The other couple tries to restore everything to its original state, to eventually respond with aggression, giving rise to a rapidly escalating conflict.
