John is a wealthy but ignorant old carpenter, who is jealous and highly possessive of his eighteen-year-old wife, Alisoun.
Nicholas, who studied astrology and was well acquainted with the art of love. Alisoun and him begin flirting. He then begins to cry, and after a few sweet words, she agrees to sleep with him when it is safe to do so
A merry, vain parish clerk named Absolon also fancies Alisoun. He serenades her every night, buys her gifts, and gives her money, but to no avail—Alisoun loves Nicholas
Nicholas gets his night with Alisoun but its interrupted by Absolon. He is tricked into kissing Alisoun's butt and he then burns Nicholas's butt.
John hears the commotion happening and when Nicholas yells "Water!" he thinks the flood is coming and cuts the rope from the bathtub
In the end, Alisoun gets off, everyone thinks John is crazy, Nicholas has a burnt butt and Absolon kissed a bum.
