The film starts with a woman on the run from her millionaire husband giving birth to a daughter in the home of a washerwoman. The woman dies in childbirth, but the baby survives. The washerwoman leaves the baby in a horsedrawn Parisian taxicab (No. 13). The paperwork of the birth is lost in a huge tome. Sixteen years pass. The tome is bought by a poor student. One day his bookshelf collapses, and the tome opens at the page where the paperwork has been hidden. The student realises that the paperwork relates to a millionaire who has spent the last sixteen years looking for his pregnant wife. The student traces the washerwoman, and he tricks her into confessing what she has done with the baby. Meanwhile, the baby has been adopted by the cab driver and his wife, and has grown into Lili Damita.

'Love and the First Railway' is what this movie's title would mean in English. This is one of those films that depicts fictional characters participating in an historic incident. The actual first railway was built in England, of course. But according to this movie, the first railway (in Germany, at least) was built from Berlin to Potsdam, in 1838. I haven't the faintest idea if that's correct, but the people who made this movie do seem to take a great deal of interest in historical accuracy, so I'll take their word for it. Anyway, a title at the beginning establishes that this movie is set in 1838.

Deviating from the historical facts, Lola is introduced as a young Spanish “Gypsy” who becomes involuntarily embroiled in an attempt to poison the Infante of Spain (a short but splendid cameo by Heinrich George). As a result, she has to flee the country, arriving first in Italy, where she is taught how to act like a lady. Later, in Paris, she is invited to dance at the city’s prestigious opera house, becoming a worldwide sensation. She then becomes secretly involved in a revolutionary plot by Louis Napoléon, the future emperor of France. When the plot fails, Lola is once again forced to flee, this time to Munich, where she captures the attention of Ludwig I. Their ensuing affair arouses a great deal of hatred among the people and the establishment, however. In the end, Lola has no choice but to leave again, and vanishes into the night mist.

Clemens and Bobi, two legation secretaries, are sent on a delicate mission by their minister: it concerns a red portfolio with secret papers, which the minister stuck under a bed mattress and forgot about when he met someone on a rendezvous. And to make things more difficult, the horny minister can't remember which room he left it in. After several incidents in different hotel rooms, neither secretary has found a thing. There's not a trace of the portfolio; but Clemens is more interested in Annette, the young lady in one of the hotel beds, than in the portfolio. He forgets his mission and can think only of her. Boni, in the meantime, has found his way into a room, where Olivia is staying and sees a red, leather folder there. But the woman throws him out in short order.
