The best short on here, by far, is "Touch". It is in no way an easy thing to watch, but it is so incredibly engaging and heart-wrenching. The nameless lead character, played with amazing believability by Brendan Fletcher, never speaks a word of dialogue in the film itself. Instead he narrates the entire short in form of a voice over, detailing the thoughts going through his head and the situations around him through his own viewpoint which has been warped from years of abuse and captivity. This is one that is deeply disturbing, but it will leave you in complete awe of how well the entire thing is acted and filmed.
