Now here's a way to throw your players for a loop. Send them on a rescue mission. Make them battle monsters, infiltrate heavily guarded fortresses, and evade cunning deathtraps to get to where the captives are held.

And when they get there, have the rescuees not want to be rescued.

Anything can happen from there.

{The Tatooine desert, night.}
GM: You've found the Sand People camp.
Anakin: I use Force Sensitivity.
GM: You feel Shmi's presence in one of the tents.
{Anakin finds the tent and cuts his way inside with his laser sword}
[SFX]: Cshwoom!
Anakin: Mother! Are you okay?
Shmi: Anakin!
Anakin: Have they hurt you?
Shmi: I... <cough> I'm okay. You must leave.
Anakin: I came to find you. I'm taking you home.
Shmi: No! Go back and tell Cliegg they're holding me for ransom.
Anakin: I'm not leaving without you.
Shmi: You must. This can be resolved without bloodshed.
Anakin: They should have thought about that before they took you.
Shmi: This isn't like them. They're a peaceful race, really. They've been corrupted.
Padmé: So they're worth XP now?
