Egeus addresses to Theseus that Hermia cannot marry Lysander and she has to marry Demetrius. Theseus comes to conclusion that Hermia can either marry Demetrius, become a nun, or be sentenced to death.
Lysander thinks of the idea of him and Hermia to go to the forest to get married ,so they are not under Athenian rule. Hermia tells Helena and Helena tells Demetrius. Demetrius and Helena then search for Hermia and Lysander in the forest.
Lysander and Hermia fall asleep. Puck is ordered by Oberon to put a potion on an Athenian males eyes. Puck was supposed to put it in Demetrius, but ended up putting it on Lysander instead. This then makes Lysander love Helena.
Puck and Oberon realize the potion is on the wrong male. While Demetrius and Lysander are looking for each other to fight because they both love Helena, Puck creates darkness and fog and mixes where their voices lead. The four of them then fall asleep and the antidote is placed on Lysander's eyes.
The four lovers wake up remembering everything as a dream. Lysander loves Hermia again and Demetrius loves Helena. Theseus, Hippolyta, and Egeus find them in the forest and come to conclusion they will be having a triple wedding.
Theseus and Hippolyta get to have their wedding with Hermia, Lysander, Demetrius, and Helena.
