Based on notorious real-life "lonely hearts killers" who make victims of their romantic liaisons, Alleluia is a dark and fascinating love-story-gone-wrong from Belgian horror maverick Fabrice du Welz. Michel (Laurent Lucas, With a Friend Like Harry and Calvaire) is a born womanizer and professional hustler with a penchant for wooing lonely, vulnerable widows and divorcees. When he meets introverted single mom Gloria (Lola Duenas, Volver and I'm So Excited!) online and treats her to an electrifying first date, she's left completely smitten. Michel tries to swindle what he can out of the one-night stand, but his latest victim has other plans. Basking in the rush of new love, she frantically pursues him, witnessing the true depths of his depravity and offering herself as an accomplice in his seductive crimes. Having truly met their match in each other, the unhinged lovers embark on a deadly odyssey amplified by wild sex, unbridled jealousy, and passionate forays into the dark arts. This smart and gory shocker breathes new life into the lovesick horror genre to serve up a chilling tale of white-hot desperation and terrifying devotion.
