When carefree drug dealer Darius stumbles into what looks like a drug deal gone horribly wrong, he snatches up a bag of weed, hoping to use it as a ticket to leave town with his girlfriend Vanessa. But when he organizes a quick sale to a local scumbag and his hangers-on, he finds the drugs have some rather unsavory side effects. Surrounded by clients that are slowly morphing into bloodthirsty monsters, Darius and Vanessa have their relationship, and their lifestyle choice, tested in a very serious way. Part brutal zombie thriller, part bizarro stoner comedy, Just Say No is a Christmas-themed genre treat for all audiences.
