Horns

This film is sad.  You should know this going in.  Beautiful, angelic Merrin (Juno Temple) is dead, and her long-time boyfriend Ig (Daniel Radcliffe) is out on bail, awaiting trial for the crime.  With the whole town presuming him guilty, he has no hope to find the real killer and clear his name - at least, not until he wakes to find horns sprouting from his head.  As anyone who sees them starts to share their innermost confessions, and take suggestion to do bad, Ig must imbrace his inner devil to trace the events leading to Merrin's death and find the real killer.
