The Warehouse Downtown

Arson in the run-down part of town (from some source...) burns a warehouse. This was some sort of secret facility/storage warehouse/something belonging to Somebody Important. A VIP hires the runner team to run a 24-hour watch on the place and discreetly take out anyone who comes snooping around or tries to steal from the place. They can't post regular corp security without blowing the nature of the place.

The PCs must decide whether to take the job (and consequently maybe go up against other runner teams) or to betray the VIP and loot the place themselves (putting them on the other side of the fence).

Complications: the police show up and try to do an investigation; the PCs must also track down the arsonist to find out if it was really intended to expose the facility; etc.
