The story of Lehi's Vision is narrated almost exactly as printed in The Book of Mormon, with scripted interpolations depicting the reasons some people might have for either holding onto the Iron Rod or choosing otherwise.
The video also adds scenes of people rescuing some of those who have fallen away.

NOTE for the series: we chose not to buy these when our children were young, not just for the expense (contracted for the entire series), but because we didn't want them confusing cartoons with scriptures.
As an adult, I am enjoying the art, music, and writing. I think they are best suited to middle-schoolers, who are past the age of belief in make-believe, but not so old (teenagers!) as to find them too childish. ( )
