Uh, try on Netflix, but also just hunt around for streaming sites, I'm sure you'll find something.
It's basically about these guys called contractors that have "magical" abilities that come at the cost of something. For example, one person has to break a finger every time he uses his ability. Other contracts include having to fold all the corners in a book, arranging stones in a 6 x 4 pattern, etc, etc.
The overall plot is that some super secret key has appeared that'll lead through the Gate, which is another other worldly object that just appeared out of no where and is believed to be the catalyst for the creation of the contractors. It focuses on a single man who aims to find this key anyway possible, even through lethal force.
