The depressive nobleman De Biel marries the cheerful Emma. She’s already been engaged three times, and her last fiancé hanged himself because she cheated. After the wedding the bride and groom continue to celebrate with a small group of people, the last of whom to remain are the priest and the musician Mario. According to an old custom, the last guests are allowed to make one wish before they leave. The Abbé’s wish is to see Emma ‘as God created her’, and he and Emma proceed to pleasure each other in the bathroom.
 
Then the Abbé’s carriage arrives, but the diminutive musician Mario gets left behind and has to spend the night with the newlyweds. Before they go to bed, the groom confesses to his bride that he is no longer able to consummate the marriage tonight. Emma turns to the little musician, who sadly after four bouts of lovemaking is crushed to death by the very large bride.
 
At the funeral service three days later, the Abbé gives the bride a lot of ‘comfort’, and comes to stay with De Biel and Emma as a permanent guest. After eight and a half months a child is born that already has long hair and can talk. The Abbé confesses that the child cannot be his as he is infertile, nor is it De Biel’s. Emma is so outraged that she throws the Abbé out, who proceeds to hang himself.

The Epilogue image shows the funeral of the Abbé, who is now burning in hell. Mario floats in heaven as an angel with a mandolin, and proudly looks down on his son, who at three months can already walk and play the mandolin.

Cuck’s Hot Wedding Night is darker than most of Lelek’s work, the action taking place at night by candlelight. He explains that this is ‘black humour in a dark time’ – whether he means then, now, or both, is not clarified.
