What is +1 (2013) about?
+1 follows three college friends who head to the wildest party of the year, only to encounter a bizarre supernatural phenomenon that creates duplicate versions of every partygoer. What starts as a night of fun quickly becomes a terrifying fight for survival, testing friendships and sanity in equal measure.
What does the duplicate phenomenon mean in +1?
The film's central mystery involves a strange event — likely tied to a meteorite or electromagnetic anomaly — that causes time to loop and creates copies of everyone at the party. The duplicates gradually catch up to the present, raising the unsettling question of what happens when you come face to face with yourself.
Where can you stream +1 (2013)?
You can stream +1 on YouTube TV, Philo, or Kanopy for free. If you'd rather own or rent it, it's available on Apple TV Store, Google Play Movies, and YouTube. Plenty of options depending on what works best for you.
Does +1 have a satisfying ending?
+1 wraps up with a deliberately ambiguous and unsettling conclusion. Rather than offering tidy answers, the film leans into its sci-fi premise to deliver a finale that prioritizes atmosphere and dread over resolution — the kind of ending that lingers and invites debate long after the credits roll.
Who are the main actors in +1?
The film stars Rhys Wakefield as David, Logan Miller as Teddy, and Ashley Hinshaw as Jill — three friends at the center of the chaos. Natalie Hall, Suzanne Dengel, and Colleen Dengel round out the key cast, with the Dengel twins playing a particularly memorable dual role.
Is +1 worth watching for sci-fi thriller fans?
+1 is a solid pick if you enjoy genre-blending films that mix party-movie energy with unsettling sci-fi concepts.

It's not for everyone, but fans of slow-burn sci-fi horror will find plenty to enjoy.
Who directed +1 and what else have they made?
+1 was directed by Dennis Iliadis, the Greek filmmaker best known for the 2009 remake of The Last House on the Left. With +1, he shifted toward sci-fi thriller territory, co-writing the script with Bill Gullo and demonstrating a strong command of tension and visual storytelling.
