A gyilkosok (1974)

During a custody lawsuit, a husband mentions that his wife has killed their second child, which his wife doesn't even try to deny. The next time they meet is at the criminal trial, where, strangely, no one finds anything wrong with the case, not even the husband thought he could harm his wife by saying this. The indifference of those involved in the crime and the fact that they take this for granted shocks the court.
