The Secret In Their Eyes (2009)

Winner of last year's Best Foreign Film Oscar. An Argentinian police detective is assigned a rape and murder case that quickly comes to nothing thanks to corruption and red tape. Years later and retired, he revisits the case as a possible subject for a novel. All the shitty memories that surrounded the case come back to the fore, including some unfinished personal business involving an unrequited love. Pretty great, despite a penchant in Spanish-speaking culture for melodramatics (the ending, while totally satisfying, is a little hard to believe). It chugs along with a nice mixture of action, romance, drama, and dark comedy.
