Egeus and Hermia have an argument and Egeus says that Hermia is not allowed to marry Lysander.
Lysander and Hermia leave athen so that they could be together. Lysander and Hermia are followed into the forrest by Demetrius and Helena.
The king and queen of the fairies Oberon and Titania fight over who gets to keep a young boy. This causes Oberon to become angry and he makes Titania fall in love with a mana with a donkey's head.
After the potion is put on Titania it is then put on Lysander and Demetrius which causes them both to fall in love with Helena.
Lysander is given a potion so that he is no longer under the affects of the love potion and he goes back to normal and loves Hermia again. Demetrius is not given the other potion and is still in love with Helena.
The lovers all return to Athens to get married all together and watch a play.
