Egeus brings his daughter Hermia and Lysander(the man Hermia loves) and Demetrius( the one Egeus wants to marry Hermia) to ask Theseus for guidance.
After fighting with Titania and putting the potion in her eyes, Puck puts the potion in Lysander's eyes as well and he wakes up and loves Helena, leaving Hermia confused
Then Puck turns Bottom into a donkey to make fun of him which scares of his acting buddies. he wanders to Titania who wakes up and loves him.
Oberon and Puck watch as Hermia, Helena, Demetrius and Lysander come together. Oberon gets mad at Puck and puts the love potion in Demetrius's eyes himself so he falls in love with Helena and then Helena thinks they're mocking him and gets mad at Hermia. The girls fight and the boys fight.
Then Oberon and Puck make everything right by making Lysander fall in love with Hermia. They all wake up and go back to Athens.
Then everyone is happy and along with Theseus and Hippolyta, Hermia and Lysander and Helena and Demetrius get married. The end.
