Six months after the last part of her investigative television series for Planet 3 Broadcasting went out, Sarah Jane Smith is running scared. Meeting new friend Josh Townsend, she finds herself investigating mysterious events in the village of Cloots Coombe.
In the opening scene, Sarah Jane Smith refers to three characters who appeared in the 1981 spin-off special K-9 and Company: her aunt Lavinia Smith (who has very recently died), Brendan Richards (who is said to be in San Francisco) and Juno Baker.
