He finds solace and a place to stay with his wonderfully chaotic friend Nele (Sibel Kekilli), who knows a whole lot about saving Pandas, but is still trying to figure things out when it comes to human relationships. While Alex is contemplating his life in Nele’s messy apartment, he starts ruminating over what went wrong with his relationship: Maybe guys have to be tough and macho after all: Never, ever put down the toilet seat and use heavy duty musk deodorant? A question, which Alex’ best friend „Okke“ (Elyas M’Barek) a lovable wannabe-macho would answer with a manly: “Yeah!“ Okke soon takes Alex under his wing, to make „a real man“ out of him. Unfortunately his various attempts and excursions into the Realm of Testosterone fail miserably. And even the mysterious Man-Coach Volker (Milan Peschel) who specializes in self-discovery in the woods is not successful.

Equipped with this burgeoning insight and unexpected, new, honest-to-goodness love, Alex slip-slides his way past near catastrophe and finally takes the most important turn of his life in a brand new direction: Toward himself.
