Need help finding a movie that I saw a brief preview of within the 10minute freeview on

In the scene, a girl slips out of a rowboat into the lake/river and pretends to drown. A guy runs into the river and pulls her out to the riverbank. He then fondles her tits and then picks her up - and the freeview ended!

I think the movie is plot based.
It might be historic as I think it's set around a castle.
