Girls are dancing in the woods to witchcraft, attempting to kill John Proctor's wife. Reverend Paris finds his niece Abigail and the girls dancing and stripping their clothes.
Betty, involved in the witch ceremony, becomes deathly ill. She talks evil things while unconscious. Abigail threatens her and the girls not to say a word about it. Abigail also talks to John Proctor, trying to get him back. The town suspiciously think the girls are witches but they deny it and start accusing innocent women.
John Proctor and Elizabeth bring up his affair with Abigail. She catches him in a lie and is upset and afraid. They both know she is behind the accusations and want to expose her to the court.
Reverend Hale visits the Proctor home to interrogate their intentions and to look for proof. A poppet is found that Mary Warren had placed. They use this as evidence that Elizabeth voodoo'd the poppet in order to hurt Abigail, although Abigail stuck a needle in her own stomach earlier that day, accusing Elizabeth. Cheever comes and takes Elizabeth away to jail along with the other innocent women.
People are brought to the courtroom. Ninety-nine people are now accused of witchcraft. Mary Warren was going to confess that Abigail was behind the poppet and was lying, then turns against John Proctor and takes her side again. John confesses lechery.
The town is getting hung or is locked up. John confesses about seeing the devil but does not want his name to be taken from him. He rips up the confession that he signed leading to him getting hung along with Rebecca Nurse and Martha Corey.
