After many days the kids are taken out of the wagon. They have to wash their clothes and wash themselves in cold water. After that, the girls are taken to Barracks 7, their new home. There's dirty bunk beds, and one small heater that doesn't work. All the girls are instructed to sew a OST sign on their dresses.
Lida finds out that people from the Northeast in Europe are considered to be Russian. So when she goes to get food, they get the worst food because she is considered to be a Russian. Lida gets assigned to work in the Laundry place, she sews clothes for soldiers and for Inge, her boss.

They snuck in dirt to make the bombs instead of gunpowder. Then one day the factory exploded. Lida thought that she wasn't going to get away with her friends, but because she stayed, it brought her to a better place.
Soon the Barrack that Lida was in got bombed. Lida ran out with her friend Juli, and saw that she had a gun. There was a officer, at the same time they fired. They both killed themselves, but Lida had to continue. A couple months passed and Lida was in a new factory. And soon enough that got bombed also.
