Shutter Island (2010)

When a patient goes missing, a couple of marshals visit the island mental facility to figure out what happened. No one seems to be completely forthcoming and there's some suspicion about a secret facility in the lighthouse. To make matters even worse, a hurricane's brewing, which means no one can leave the island for a couple of days.

Within the first 15 minutes I said "here's what I think is happening..." and proceeded to get roughly 85% of the plot correct. So, though it looks great, it was pretty obvious what was going on from the moment the head doctor gave the marshal some aspirin.
