I was looking for a movie title.
Maybe you can help me.

The movie is post apocalyptic.
From 1980 or 90s
Mad max type guy fighting a bad guy.
Story is more about a young man with a crystal searching for his sister or girl.At the end thethe bad guys on motorcycles chase them back to a cave that leads to and underground oasis and waterfall,which is hidden from the above grounders since water is scarce. There is a whole group of water people who live there. The story is the girl wandered out years ago and was captured by the main bad guy and became his girl and they want her back.
I have been told by many that it is called Stryker, bought it, watched it , that is not it.



Any Help

Thanks

One other possibillity could be:

Shepherd (1999) - Plot summary

FYI: There are two movies named "Stryker." Could you have bought the wrong one?
