Thick black clouds fill the sky over Cardiff. When twenty-four inches of rain fall in twenty-four hours, the downtown drainage system fails. The capital's tramps are killed, their mutilated bodies left lying on the wet streets in the vicinity of the Blaidd Drwg nuclear installation. Pursued by Torchwood, the killer calmly falls from a height of eight floors and dies. But the killings don't stop. The investigation leads Jack Harkness, Gwen Cooper and Toshiko Sato to a monster in the bathroom, a mystery at a military base and the hunt for stolen nuclear fuel packages. Meanwhile, Owen Harper disappears from the Hub when a game of "Another Reality" leads him to an old girlfriend... Something is approaching, seeping through the Rift, straight into Cardiff Bay.
