"We need to practise for later on, for real life. We need to know everything so nobody can ever mess with us."

Nini and Jameelah are 14, best friends forever. This summer they're going to grow up, together, on their terms. But things don't always turn out the way you plan. As the summer holidays stretch out before them, Berlin becomes their playground. At night they descend on the red light district, impersonating the prostitutes there in order to practice for their first time, giggling to each other, tipsy on Tiger Milk. But then, one night, Nini and Jameelah witness a crime that threatens to ruin everything. Tender, funny, shocking and tragic, Tiger Milk captures what it is to be young.
