This one may not have much of a plot, but, characteristically for director Hans Billian, it sure has a lot of action, with one very softcore scene chasing the other. After a minimal setup ("Cat Burglar!" -- "Don't hand me over to the police, let's get it on!" -- "Owright!"), the actors get out of their kit faster than Superman when he gets his signal, followed by an explicit but hectic and rather mechanic sex scene. The girls are pretty and willing, the men generally revolting, the dialogue is inane, and everyone is so hyperactive and super-jolly as if they were tripping on amphetamines -- it's typical for a German porn movie of that era that the atmosphere is agitated and forcedly silly, rather than sultry or seedy.
The plot goes like this: a schoolgirl has eloped from her parents and checks in at the hotel "Liebesnest" ("Love-Nest") with her boyfriend to do the dirty. When the inept Lothario dumps her without paying the bill, she signs on as a chambermaid to get paid and laid through the hotel's special roomservice. When her dad finds out about her job description, the hotel staff set him up with another chambermaid and blackmail him to allow his daughter to pursue her professional aspirations. Eventually she finds a beau and resigns her position, but not before having come up with a suitable replacement to fill her vacancy. In between there are plenty of subplots, such as an female cat burglar (who contents herself with small change, apparently) and a surreal masturbation scene with two taxi drivers, who are surprisingly comfortable around each other.
I kind of liked the trashy visual style of the movie, the dowdy interiors, the garish colours, the single-floodlight-lighting, the silly mail-order-catalogue costumes. The entire movie takes place in the same run-down building and over approximately 24 hours, which will please the adherents of the Aristotelian unities of space, time and action.
Hans Billian may not have been an artiste, but he sure was an artisan who could get the most out of a thin budget. He always saw to it that that the punters got their ticket money's worth.
