People go missing every day, but in severe weather the numbers increase. When Kayleigh Harwood, a young hairdresser, is reported missing by her mother in the worst blizzard Harrowfield has experienced in years, D.I. Jack Dylan and his team are called in to assist. Kayleigh's car is found abandoned with her mobile phone inside, but there is no sign of her. Clothing is found on nearby moorland and a search of the local quarry begins. The investigation turns to a loner living in a dwelling close to where Kayleigh's car was found. As the snow thaws, human remains are found, and Dylan's boss Chief Superintendent Hugo-Watkins, thinking the two incidents are linked, calls out the entire Major Incident Team, much to Dylan's disbelief. Meanwhile Dylan's wife, Jen, becomes distracted and distant as unbeknown to Dylan her ex fiancé is in their midst and stalking her.
