Pilot: The Death of Sarah Jane Smith

It's been 8 years since mum died. But we haven't stopped defending the Earth in her honour. She may be gone but her legacy lives on. What happens to the world when Sarah Jane Smith is no longer among us? We do. I'm Luke Smith. That's my adopted sister, Sky. Our friends Clyde, Rani and Santiago. Our dog K-9 and our supercomputer Mr Smith. We stop aliens from destroying the planet in the name of Sarah Jane Smith.
