BERLIN 1961
Anja and Monika live opposite each other. They play together every day, with Otto the cat.
One night they wake up to bangs and shouts. Soldiers are building a huge barbed wire fence between them. A terrible forever wall that gets longer and higher until it divides the whole city.
On the East side, Monika is scared – neighbours are becoming spies and there are secret police everywhere.
It’s Anja who spots that Otto has found a way across. If he can visit Monika, then perhaps she can too.
But Anja gets trapped and there’s no safe way back . . .
