The date of the Doctor's death approaches (again), and in the last few days of his life he decides to pay a visit to his old friend Craig Owens (who just happens to be James Corden. AKA jammyness personified). However, when people begin to go missing and a mysterious silver rat appears in a department store, the Time Lord is pitted against one of his oldest and deadliest enemies.... The Cybermen! Closing Time is followed immediately on BBC Three by this week's Doctor Who Confidential.
