Six-String Samurai(1998)

Synopsis

In a post-apocalyptic world where the Russians have taken over a nuked USA and Elvis is king of Lost Vegas, Buddy is a '50s rocker and wandering warrior rolled into one, too-cool package. Armed with his six-string in one hand and his sword in the other, Buddy is on his way to Vegas to succeed Elvis as King. Along the way, he saves an orphan who decides to tag along.
