Synopsis Edit

Part 1 Edit

Clyde and Rani wake one day to discover that they are the only survivors of the human race! The whole of Earth is empty – even Sarah Jane has vanished. A deserted London holds terrors of its own. Strange forces lurk in the shadows as mysterious visitors approach!

Part 2 Edit

Clyde and Rani meet their enemy as the Robots arrive on Earth. What do they want, and where has the human race gone? It’s a race against time, but without Sarah Jane’s expertise, Clyde and Rani must trust each other like never before if they’re to save the whole world.

Plot Edit

Part 1 Edit

Sarah Jane tells Mr Smith to do a maximum scan. Clyde asks what is going on. Rani tells him that Mr Smith picked up an alien energy trace for a second, then it vanished into the signals of every energy source on Earth. When they leave Sarah Jane's house, Rani reminds Clyde of their school assignment. Clyde sees no point in doing the reading considering they might be invaded. Rani's dad comes to see her in her room, but she asks him to leave so she can finish the assignment. Clyde's mum also comes to see him. She compliments him on his latest cartoon drawings.

As they sleep, the mix of signals and sounds transmitted across Earth is suddenly cut out. Rani wakes to find her parents missing. She sees no-one on the street. Sarah Jane is also gone and Mr Smith does not seem to be in the computer that houses him. Rani searches for another person. She finds nothing has a signal any more. She prays she is not alone. She hears a knock at the door and opens it to find Clyde. They head into town to look for someone besides them.

They can't find anyone and realise that if everyone suddenly disappeared, there should be crashed vehicles everywhere. There are not, which means that whatever took the humans didn't want to do any damage. They go to a cafe for breakfast and try to figure out why they have not been taken. They decide to return to the attic, but notice crates being knocked over. They spot another person, who runs away. Giving chase, they follow him to an apartment block. He is a schoolboy called Gavin who has been living with his aunt and uncle since his mother died, his father having disappeared. Rather than being relieved to see other people, Gavin is afraid of Rani and Clyde. They try to convince him they mean no harm and Rani tells him about aliens to try to gain his trust. Gavin is sceptical. As they try to persuade him to help, a strange noise is heard. Gavin slips away while Rani and Clyde try to work out what it was. Clyde points out a couple of strange facts about Gavin... he should have been happy to see other people on Earth rather than afraid. Also, his room is almost bare and there are no pictures of him with his aunt and uncle indicating they care little for him.

They go back to the cafe and see a strange image on all the screens, even the mobile phones. They hear a noise getting closer and investigate. Rani notices Gavin and goes down an alley; Clyde looks around the corner and sees a yellow robot. It corners him whilst Rani is cornered by a red robot. The robots both lift their arms and point them directly at Rani and Clyde...

Part 2 Edit

Gavin pushes the robot facing Rani against the wall so they can escape. Clyde runs away from the yellow robot and hides in a store. He evades it and meets up with Rani and Gavin. They look at the images on the screens and go in search of the robots, then decide to return to the cafe. Rani and Clyde talk about what makes them different, mentioning time fissures, space travel and the TARDIS, much to Gavin's confusion. All of these things pertain to Sarah Jane as well, however. Clyde then remembers something that connects only him and Rani... during their encounter with the Judoon, the two were given a ticket forbidding them from leaving Earth hence it would be illegal to remove them, which is the only logical explanation why the robots left them behind. This doesn't explain why Gavin is still there; he knows nothing about aliens.

The robots burst into the cafe. The three children escape out the back door. Rani and Clyde tell Gavin to get away, thinking the robots must be after only them. The two split up to distract the robots. They are each cornered again. The robots scan them, but do not kill them.

In the cafe, Clyde shows the robots a newspaper so they can learn the language quickly. The robots reveal that the strange image is a countdown. They demand the "sun and air", saying that if it is not given to them by the end of the countdown, the human race will not return. Clyde and Rani are confused by the robots' demand, but then Rani realises that they aren't saying "sun and air", but "son and heir". It turns out that Gavin's dad was an alien king. He has died. The robots have come to take Gavin to their planet. They sent the news in the energy trace from the previous night, but Gavin never received it.

Clyde and Rani search for Gavin, finally locating him at the Ealing Circle Nature Reserve. The robots cannot see him. They determine that Gavin is wearing a bio-damper ring to shield his alien half; when this is removed, the robots send him the information again, showing him the planet he is meant to rule. Gavin agrees to go. He orders the robots to return everyone to Earth. He bestows upon his new friends the titles Lord Clyde and Lady Rani before he leaves.

Everyone returns to their rightful places. Mr Smith fixes the records to indicate that Gavin has moved to Australia. Clyde and Rani think about the fact that if they had never met Sarah Jane, they would have been in big trouble.
