Park Days 

A derealized homeless man named Daniel Park returns to his senses following a miraculous event witnessed by a group of young cyber hipsters. Assisted by the generosity of their unofficial group leader, photographer and self described "hacktivist" Jack Rosenblum, Daniel sets off on an accelerated quest to unravel his past. With each truth uncovered, Jack finds himself increasingly distanced from Daniel, a man he quickly realizes is hell-bent on reconnecting with Escapea rare psychedelic drug that when consumed results in a dreamlike reality that lasts months, possibly even years.
