The poem tells the story of a frog and nightingale in Bingle Bog. The frog loudly croaks every night, annoying the other creatures, until the nightingale's beautiful singing captivates everyone. The cunning frog then convinces the nightingale he can train her singing, but he relentlessly criticizes her and overworks her for his own profit. Though the nightingale's singing brings crowds, her declining health and the loss of her original style leads to her death, which the frog dismisses as her own fault.
