Watch Do Not Enter Full Movie Free Online 123Movies. Two working class youtubers ‘in the making’ enter an abandoned mansion to get their basketball back, and get lost inside while pranking each other. They record their ‘quick adventure’ with their phones for their audience, and tweak it with a fake phantom appearance to attract more followers to their YouTube channel. When uploaded the video goes viral, so they start a challenge: if the video reaches a certain number of views, they will enter the house again, at night, alone, totally unprotected. As fans react positively, they will do as promised, not only to discover and unveil the true nature of the place and their inhabitants, but to realize they might not be among the living anymore. Which opens a question - how far would you go to be famous?
