The plot is basically wherever it goes. The last holy grail was naturally not found. In fact, King Arthur didn't even see the shadow of the Holy Grail in the whole movie. The director set up this plot just for funny service.
The animation part is basically nothing funny, mainly to connect the plot. The whole film has a single scene and the shooting cost is estimated to be very low.
This is the second film of the Python comedy group, and one of their best feature films. "Brian's Life" is their other top work.
