It's Dark Here is the true story of Jason Tennies, an extremely gifted and accomplished young man -- a black belt in karate, a college student, a talented musician and most especially, the beloved only child of David and Linda. When Jason inexplicably and without warning suffers a schizophrenic break, his parents scramble desperately to get him the help he requires. In five short days, they must watch helplessly as their beloved son disappears before their eyes. As they endure this nightmare, they cannot help but reflect on happier times and what might have been while also facing the potential outcome for their family.
