Season 3

Under pressure from Goodtimes, Moritz races to rebuild MyDrugs during a school trip to the woods, but code bugs — and allergies — derail his progress.

Lenny helps Moritz with the site on one condition: that they keep their collaboration a secret. Meanwhile, Jens frets about his son's future.

Moritz hires a high-priced business consultant. Kira and Dan come up with new ways to raise money for Lenny's medical treatment.

The guys take a road trip to Rotterdam. Marie asks Lisa to keep an eye on her brother. When Moritz crosses a line, Dan does damage control.

To celebrate the end of their Abitur exams, the students throw a costume party at school — and things get a little out of control.

A high-stakes situation leaves the friends scrambling to figure out their next move.
