Taxi driver Peter Basse is a jovial and cheerful man who faithfully looks after his daughter at the wheel and steers his carriage through the streets of Copenhagen with unwavering composure. One day he drives for the stylish valet Johan, employed by the old Dowager Baroness von Hessen. The taxi driver is tasked with delivering an important letter to the Dowager Baroness's grandson. Along the way, Peter Basse learns that the Dowager Baroness may be going crazy. In any case, she has made the acquaintance of two spiritualists.
