Robert works as a gamedev in Hamburg and, together with his team, which includes his best friend and flatmate Ole and his girlfriend Lorna, is on the verge of completing an innovative first-person shooter.

On the spur of the moment, he goes to a nearby dry cleaner and asks the ladies working there for quick help.

Robert's reaction seems a little strange, but no one can yet suspect that he has just fallen head over heels in love with the attractive woman in her mid-forties.
