Red-Letter Days.

Mihály, a retired foundryman has brought up his sons in a very disciplined and strict way, and as a result they have become a doctor, an engineer, and a teacher. However, his half orphan grandson, Misi, has been spoilt, and become skilled in nothing else really but riding his motorbike and going to parties. He has been involved in shady businesses a number of times already. Having experienced so many difficulties, privation and hardship in his own life and now seeing Misi's irresponsible lifestyle, the old man's bitterness is growing day by day.
