Hey Playground.

I have a one-shot session coming up on Monday, and my Well of Inspiration is out of charges. Maybe some of you have some ideas kicking around in your skulls.

TL:DR: Give me some ideas for a heist/caper one shot.

Here's the deal. My campaign is on a brief hold, and during our downtime, the characters are going to have a month of downtime. One player already decided that during that month he unwittingly became involved in the drug trade in our city, and spent some time in jail. On Monday, I'm going to be doing a one-shot with the group that takes place during the downtime, and would like to play out that story. He will be playing his normal character - a 4th level Lizardfolk Battlemaster, who's never been out of the swamp before. He's a willing dupe in this session.

I'll hand the other players pre-gens that will represent local gang members, maybe an undercover inspector, I don't know what. They are goign to be involved in a story line revolving around the lizardfolk getting conned into making some kind of drug transaction, or accomplishing something for a drug cartel/gang, and ultimately getting pinched. But I'm at a total loss as to what this scenario looks like in its details, and how it all plays out. Spit some ideas at me regarding:

Who are the other characters, and what are their secret agendas?
What weird or spooky or dangerous locale or locales does this play out in?
What kind of enemies are we going to come up against? (there needs to be some combat or my players will be sad)
What a cool piece of info or hook they can discover during this session that I can reference back to later after the downtime is over?

Help me prime the pump, Playground, you're my only hope!
