Theseus is the Duke of Athens and is in the course of planning his wedding to Hippolyta, the queen of the Amazons. Egeus arrives with Hermia his only daughter and two other men, Demetrius and Lysander. Egeus wants his daughter to marry Demetrius, but Hermia loves Lysander and is against it. Egeus makes a declaration that if Hermia fails to marry Demetrius, she will die. Hermia and Lysander plan their escape to away from the city to Athens. Hermia informs Helena of their plan, who was once betrothed to Demetrius and still loved him. She tells Demetrius of their plan.
Some of the locals have decided to perform the play Pyramus and Thisbe at Theseus wedding. A terrible actor named Nick Bottom gets the lead role.
The fairy Queen Titania and Oberon the King argue over custody for an Indian boy that Titania is raising. Since Oberon is denied custody, he sends a troublesome jester named Puck to seek out a plant named Love in Idleness whose juice makes any person affectionate to the next creature they see.
Oberon sees how Helena is treated by Demetrius and instructs puck to pour some of the juice in the eyes of Demetrius at the moment that Helena is supposed to be the first person he sees and therefore will love her. Puck makes a mistake and puts the potion in Lysander’s eyes who first sees Helena and falls deeply in love with her.
Oberon also puts the juice in Titania’s eyes who first sees Bottom and falls for him, and she willingly grants custody. Oberon then releases Titania from the spell.
Both Lysander and Demetrius are in love with Helena. Oberon, therefore, commands Puck to create a fog, so the lovers do not find each other, and while they slept, Puck is made to reverse the spell on Lysander and also casts another spell so that they would not remember what had happened. The joyous lovers enter, and the play is performed.
