Sarah Jane has met Peter Dalton and wants him to become part of her life, as the adventure series continues; perhaps he could become a father to Luke. But Clyde suspects that Peter is hiding a secret or two, especially when he and Rani find an empty house where Peter says his home should be.

The Doctor makes a spectacular return on the happiest day of Sarah Jane’s life but a deadly trap is awaiting them all.

As the strands of a clever and careful plan come together, can even a Time Lord save Sarah Jane on the day of her arch-enemy’s greatest triumph?
