In the beginning scenes of Act I, three “weird” witches meet with Macbeth after the battle with Macdonwald. They tell him three prophecies, and his dear friend Banquo is told one.
In scene VI, Lady Macbeth warmly welcomes King Duncan and his royal court to Inverness. They act like the perfect host and hostess and don’t hint at his imminent murder.
In one of Macbeth’s soliloquy, he envisions the dagger he will use to murder King Duncan with. It is later seen covered in blood. He snaps out of his vision by the sound of a bell.
After Lady Macbeth drugs Duncan’s two guards, she takes their daggers from them and gives them to Macbeth. He goes into Duncan’s bedroom and stabs him.
After the brutal murder of Duncan, Macbeth is crowned king. His power is slowly going to his head and now wants to kill Banquo and his son, Fleance. He hires two murderers to carry out the killings.
Following Banquo’s murder, Macbeth tries to remain a calm and jovial host. As he leaves his seat, the ghost of Banquo appears in his place. He begins to talk to it and Lady Macbeth attempts to calm him and the guests.
