Please tell me what is happening. Will I get murdered?!
Don't worry! It's quite simple to understand.
Macbeth finally kills King Duncan and frames his two chamberlains, who were given wine by Lady Macbeth to make them drunk so that they won't remember the night before when they wake up. Lady Macbeth also covers them with blood to make it look like they had killed King Duncan allowing for Macbeth to take the thrown without being accused of regicide.
This is for my family you murderous traitor! ROT IN HELL!
Macbeth realizes that Banquo's sons were told to take the thrown according to the prophecy so Macbeth sends some killers to kill Banquo and his son. In doing so, Macbeth thinks that he would remain king.
At the party that was thrown for him, Macbeth sees visions of Banquo's ghost and begins to be frightened. So Macbeth goes to the three witches in hopes of finding answers. The witches tell him that he could only be killed by a man who was born through a natural birth from a woman.
Macduff kills Macbeth on the hills of Dunsinane. Macduff sought for revenge as Macbeth had killed his son and wife. He reveals to Macbeth that he was born through a a caesarean section birth, which is why he was able to kill Macbeth since he wasn't born naturally. After Macbeth's death, Macduff brings Macbeth's head to Malcolm.
