Wow. Never heard it described like that. XD
You left out some very important details, though.
Plot: It starts out in a prison thing. The evil sorceress has imprisoned many pregnant women, becuase there was a prophecy that a young girl would be born and put an end to her evil reign. So! Somebody took the baby and put her in a basket & in the river a-la "Moses". The baby floated downstream and was found by Willow & his family. Willow himself wishes to become a wizard someday, but is doomed to a life of farming. When the baby is found, his villiage makes him take her back because she isn't like them. That's how the adventure starts. Eventually, he teams up with Madmartigan & two Brownies on their way to find the sorceress that the evil gal banished. So yeah. It's a really, really cool movie and definately worth watching.
