Half Nelson

An inner-city teacher struggling with addiction forms an unlikely bond with a young student who catches him in a compromising position in director Ryan Fleck’s feature-length adaptation of his own award-winning short film Gowanus, Brooklyn. Despite his dedication to the junior-high students who fill his classroom, idealistic teacher Dan Dunne (Ryan Gosling) leads a secret life that the majority of his students will never know. When Dunne’s drug-soaked nightlife begins to bleed over into his daytime hours and troubled student Drey (Shareeka Epps) makes a startling discovery, the tenuous bond that forms between the pair soon leads to a warm friendship that could either lead them down a dangerous path or provide the human companionship needed to see things from a fresh perspective and start life anew.
