Hendrik Groen and Evert Duiker, faithful friends in good and bad times, are well over seventy and their lives have quieted down. They see each other once a week to play chess, have a drink, and grab a bite to eat while reflecting on life. But one day, their peace is rudely disturbed when Evert shows up on Hendrik's doorstep with a surprise in the form of an unexpected little guest. He had spotted a stroller with a baby in it.
