Inside (2011 film)

Inside is a 2011 American social film thriller brought to viewers through a partnership between Intel and Toshiba.
Directed and written by D. J. Caruso and starring Emmy Rossum, the experience is broken up into several segments across multiple social media platforms, including Facebook, YouTube, and Twitter. Viewers are challenged to help Rossum's character, Christina, to safely escape her predicament. The film bears some similarities to the non-social 2008 film "Untraceable" in that it involves kidnapping and an Internet audience as part of the plot.
The first in a series of episodes was released on the website on 25 July 2011 for those participating in the "real-time experience". The whole film became available for online viewing on 6 September 2011 on their website, though both the website and YouTube channel no longer exist.
Plot.
Twenty-four-year-old Christina Perasso, a tough, resilient girl, wakes up trapped in a room and has no idea where she is being held or who did this to her. She has been left access to her laptop. Through the use of an intermittent Wi-Fi signal, she reaches out to friends, family and an audience through social media. She lists facts, clues, pictures and videos to aid the audience in figuring out where she is, who her captor is, and why she was kidnapped.
