Torchwood: We Always Get Out Alive

Gwen Cooper and Rhys Williams are on the run from a cataclysm. They're the only survivors, and they're driving away from the disaster as fast as they can. They've got to get away, they've got to warn the authorities, and they just can't be late for the babysitter again.

Dim problem. After all, they're Torchwood and they always get out alive. But this time there's something in the car with them. Isn't there?
