A young girl, Betty, is in a coma-like state. Her father, Reverend Parris, is minister to the town of Salem.
It is revealed that a group of young girls led by Parris' slave, Tituba, were dancing and doing voodoo in the woods.
A townsman named John Proctor enters; it is clear that he can see through the lies of the girls, who are now claiming they know who in town has signed the Devil's black book.
The audience is made aware that Proctor once had an affair with Abigail (Parris' niece). Parris decides that he should call Reverend Hale, a witchcraft expert.
