This one’s for you sci-fi folks out there.

One of the PCs receives a text message (or instant message or email or packet transmission or some other form of instant communication) that states they will die in 15 minutes. That’s it. Just a 15 minute warning of their death. The source of the transmission is not readily available.

Fifteen minutes later, an “accident” happens that almost claims the PC. It could be a car crash, an errant light rail train, a crane collapse or something that could be written off as coincidence. Immediately after the “accident” the PC receives another transmission, “We missed. You won’t be so lucky in an hour.”

The PC (or group) now has an hour to track down the source of the transmission. Each hour this repeats itself. Each “accident” will become more and more perilous as the day drags on.

Once the PC (or group) tracks down the source of the transmissions and puts a stop to them, the “accidents” come to a sudden stop.
