Short Polish drama. Original title: Nagie oko
Trying to fill her inner void, a lonely maid is spying on hotel guests. Her desires are fueled by a soap opera she is obsessed with. One day, when the star of the episode she has just seen appears at the hotel, the dreams of the emotion-starved woman start crawling out of her imagination.

Scoop, is there any female nudity in Graduation Trip: Mallorca, new movie on Prime?
I skimmed through it and I don’t think so. That’s the bad news. The worse news is that at its heart it’s really a hand-wringing drama with a little slapstick, not the light romp you might expect from the title. Graduation trips are apparently not what they used to be. (Or at least they weren’t during the pandemic.)
Judging by the ratings it’s probably not worth watching.
I stopped to watch a scene here and there, and I think your supposition is correct.
