Unable to do anything to amuse themselves, Ben and Rachel start digging in the garden and find themselves opening a hatch.

Freddy and Polly revealed they had been put into cryonic suspension - their father had frozen their hearts and was able to make them start again.

Ben and Freddy, who had been escaping bullies who constantly taunt them partly because of Ben's stutter and partly because of Freddy and Polly's posh accents and their peculiar habits, come back to see Rachel and Polly being drugged and thrown into the boot of the car.

She finds a torch, picks the lock of the boot with a hairgrip and sprays antiseptic into the librarian's eyes.

They then get taken to a place where all the people who were working to find Freddy and Polly's father have been working on helping them to escape and Freddy and Polly are reunited with their Father, who built another cryonic suspension machine and froze himself inside it so that he would not grow old and die without his children.
