Dude, like, Macbeth meets Banquo and Fleance on his way to kill Duncan. And then, like, he sees a dagger that's a representation of his murderous intent and, like, off-screen he stabs Duncan a lot. Macbeth then goes off to tell his wife that he killed Duncan but, like, he forgot to place the daggers next to the guards, so Lady Macbeth has to, like, go do it for him because he's a total wuss. Then, like, the Porter shows up and he's the best character in the play. Macduff, like, finds the king dead and then, like, wakes up the king's kids to tell them this. Macduff, like, thinks Macbeth did it, but Malcom and Donalbain (Duncan's kids), like, run away so that they don't get killed themselves.
