Who are you?! Show yourself!! Banquo: Yes, show yourself or meet your doom!
The three witches prophesize that Macbeth will become the Thane of Cawdor and then king. As for Banquo, though he won't become king himself, his children will become so. Macbeth, however, didnt believe them.
Macbeth: I dont believe you freaks! Come on, Banquo, lets be on our way!
Banquo is killed, but Fleance escapes. Later on at a banquet, Macbeth sees Banquos ghost. This causes him to become terrified and the other Thanes becomes concerned.
Macbeth: Go away! Leave me alone!! Lady Macbeth: Keep calm dear. (To the Thanes) I apologize for this odd behavior, but my Lord isnt feeling well.
Sensing something wrong, Macbeth visits the witches once more. This time the witches tell him to beware of Macduff, not to fear any man born of a woman, and that he wont fall until Birnam woods comes to the castle. Meanwhile, the Thanes turn against him.
On the other hand, Malcolm and Macduff unite to defeat Macbeth. Macbeth had Macduffs family murdered. Unable to handle all this, Lady Macbeth commits suicide. Unmoved by this incident, Macbeth carried on with his sinister plans. Soon enough, Malcolm and Macduffs army approaches his castle disguised using branches from Birnam woods.
Macbeth: This cant be happening!! Afterwards Macduff and Macbeth come face to face.
Macduff: Enough of your evilness! You die here and now!! Macbeth: In your dreams! No man born of a woman can kill me!! Macduff: I wasnt born of a woman, I was cut off from my mothers womb early…
After a vicious fight, Macduff rips off Macbeths head. Malcolm was made king, and peace was finally restored to the kingdom.
