I think you're misunderstanding me here - when I talk about giving hints, I don't ask you to tell the plot, as there are countless other things that can give us a clue about the movie in question: year of production, character names, actors, directors, producers, locations, box office data, reviews, and so on (I guess you'll get the point now).
All right then, I still have little idea about your current picture, but I'll make a guess anyway: The Ring?
