The biblical portion of the play, a retelling of the Visitation of the Shepherds, comes only after a longer, invented story that mirrors it, in which the shepherds, before visiting the holy baby outside in a manger, must first rescue one of their sheep that has been hidden in a cradle indoors by a comically evil sheep-stealing couple. Once they have discovered and punished the thieves, the storyline switches to the familiar one of the three shepherds being told of the birth of Christ by an angel, and going to Bethlehem to offer the true Child gifts.
At the start of the play, Coll, the first shepherd ("primus pastor") arrives in a field, invoking God in anachronistic terms (referring, as the shepherds will do throughout the play, to the life and death of Christ even though at this point of the play Christ has not yet been born) complaining about the (typically English) cold weather and about his poverty and the arrogance of local gentry. He begins by saying, "Lord, what these weders are cold! And I am ill happyed" which translates as "God, the weather is cold and I am ill prepared/clothed." Gib, the second shepherd, arrives without seeing Coll and complains first about the weather and then about the plight of married men, himself included, with bawdy speculation about the lives of men with more than one wife and advice to "young men of wooing" to "Be well war of weding" (wary of marriage). He paints a portrait of his wife as a loud, heavy-drinking, alternately abusive and sentimentally pious, whale-sized woman. "By him that died for us all, I would I had run til I had lost her!" at which point he is startled by Coll. They confer about where Daw, a third, young, lazy and mischievous, shepherd, has gotten to, at which point Daw arrives complaining about employers, hunger, and about recent floods which he compares to Noah's flood.
Mak, a local good-for-nothing and well-known thief, arrives and pretends to be a yeoman from a lord. Although they recognize him from the start, he insults and threatens them by saying that he will have them flogged. When they threaten him, he pretends not to have known who they were. Mak tries to gain sympathy from the shepherds by explaining how his wife is a lazy drunk who gives birth to too many children. Invoking Christ and Pontius Pilate, Mak agrees to camp with the shepherds, and feigns to lie down among them. However, once they have fallen asleep he casts a spell to make sure they will not wake up and then sneaks off to steal one of their sheep. He heads back to his cottage and trades insults with Gill, his wife, who firmly believes that Mak will be hanged for the theft and comes up with a plan for hiding the sheep - she will put it in an empty cradle and pretend that it is her newborn child, and that she is loudly, painfully in labor with its twin, so that the shepherds will quickly give up any search.
Mak sneaks back among the shepherds and pretends to awaken along with them. They head off to take account of their sheep while Mak heads home to prepare. With despair at their catastrophic ill fortune, the shepherds realize a sheep is missing and go to search Mak's house. They are initially fooled by Mak and Gill's ruse despite Gill going so far as to say that if she's lying she'll eat the child in her cradle (as she indeed plans to). The shepherds leave defeated, but realize that they have failed to bring any gifts to the "baby", and go back. When they remove the swaddling clothes they recognize their sheep, but decide not to kill Mak but instead roll him in canvas and throw him up and down, punishing him until they are exhausted.
When they have left Mak's cottage, the biblical story proper begins - the Angel appears and tells them to go to "Bedlam" (Bethlehem) to see the Christ child. They wonder at the event, chastising each other for their collective delay, and then go to the manger where Mary (Mother of Jesus) welcomes them and receives their praise for her mildness. They each address the Child in turn, beginning by praising His authority and His creation of all things in tones of reverence and awe, but each comically shifting mid-speech to cooing, gushing baby talk, since they are addressing an adorable baby, who Coll, Gib, and Daw respectively give "a bob of cherries," a bird, and a ball ("Have and play thee withal, and go to the tennis!") The shepherds rejoice at their salvation, all thoughts of hardship and complaint vanished, and leave singing in unison.
Output: What city are the shepherds directed to go to see the Christ child?
