Plot
Part 1

Sarah Jane tells Mr Smith to do a maximum scan. Clyde asks what is going on; Rani says Mr Smith picked up an alien energy trace for a second, which then vanished into the signals of every energy source on Earth. When they left Sarah Janes house, Rani reminded Clyde of their school assignment, which Clyde saw no point in considering they might be invaded. Rani's dad came to see her in her room, but she asked him to leave so she could finish the assignment. Clyde's mum also came to see him.

The confusing mix of signals is suddenly cut out. Rani wakes up to find her parents missing, and there is no-one in sight outside. Sarah Jane is also gone, and Mr Smith no longer appears to be in the computer that houses him. Rani searches for another person, finding that nothing has a signal anymore. She prays that she is not alone, when 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, but 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 go back to the attic, and see crates being knocked over. They spot another person, who runs away, and chase him to an apartment block. He is a schoolboy called Gavin, who rather than being relieved is afraid of them. Rani and Clyde try to convince him they mean no harm, and Rani tells him about aliens to try and gain his trust. Gavin is sceptical, but before they can persuade him to help, a strange noise is heard and he slips away whilst Rani and Clyde try to work out what it was.

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 go investigate. Rani notices Gavin and goes down an alley; Clyde looks around the corner and sees a yellow robot. He is cornered by it, whilst Rani is cornered by a red one. The robots reveal their guns and prepare to fire...
