A young girl disappears on her way home from a sports club, and a short while later, telephones her parents to say she has been abducted. Croft recognises the voice of the kidnapper, and Deakin subsequently makes an arrest, but the kidnapper refuses to acknowledge where the abducted girl is hidden. When they discover she is being held in an airtight van, they realise time is slowly running out and the girl could soon suffocate.
