A small town shortly before the end of the GDR: 15-year-old Ulla lives with her mother in a dilapidated old building where not even the electricity works properly. Economy of scarcity and national bankruptcy are visible everywhere. Only higher party comrades live in the lap of luxury. When Ulla meets Winfried after a summer bathing trip, the two fall in love. Winfried is the son of an influential general director and owns things from West Germany that others only dream of: a computer, a games console, a walkman. On an excursion with her biology class, the high school student discovers that a dacha is being built in the middle of the nature reserve and the creek has been dammed. Winfried's father turns out to be the culprit, but the mayor is on his side. Ulla rebels against this environmental destruction connected to political corruption and organizes a protest. Her activism not only endangers her own future, but also her first great love.

As Liz and Jess debate using Jess's brother as a sperm donor, Liz's true feelings about Jess's family begin to surface, tail spinning their once-solid relationship into nosedive.
