American graduate student Randi Wallace travels to Britain to study mythology with Professor Ian Matheson. She arrives expecting a stodgy old academic, but Ian is young, and the two are immediately attracted to one other. That complication quickly pales when Randi spends a night camping on the Moors and is bitten by a werewolf. For the rest of the series, Randi and Ian investigate supernatural phenomena together while they search for a cure for Randi's curse. Eventually, their search takes them from British academia to American television, when they move back to Randi's native California, and Ian becomes host of a trashy television talk show focusing on psychic phenomena.
