Nixon and Hunter investigate a distraction burglary at a telecommunications warehouse, but Turner is forced to step in when Hunter's son is taken ill. Their first major lead in the case comes in the form of an engagement ring left behind at the scene by one of the perpetrators. However, their real breakthrough doesn't come until they discover one of the perpetrators has a penchant for phoning adult sex lines whilst the burglary is being committed. Meanwhile, Ackland and Stamp investigate when an elderly resident at a care home disappears, along with the caretaker - and her life savings, and Walker is furious when the CPS drop the case against serial rapist Keith Durante.
