Dasha and Dillon play a married couple (which they are off-screen) visiting Prague. After they fuck in their hotel room, he emerges from the shower to find his wife has disappeared. He spends the rest of the movie trying to find out where and why.
The vanished lady is always an interesting premise, but here there's not a lot of clarity. Instead, there's sluggish pacing and zero suspense, not to mention wooden acting (in English) by the Czechs in supporting roles.
Dasha is the best of a lot of fine-looking women. The sex is efficient in the Europorn style, heavy on the anal, and that may be enough for some.
