Fifteen-year-old Stephen snatched a toddler from a park and held him captive for five days in his Grandfather's house. Three years later, his mother Sandra is forced to piece together what happened - and why. While she tells their story to a documentary camera; her estranged son tells an altogether different story with the camera. 'SNAP' presents us, as well as its characters, with a compelling mystery. We begin to assemble an unsettling portrait of three generations of a family trapped in recreating a past that each one denies. It is only when the image of Sandra and Stephen's likeness is captured and reflected back to them that - SNAP! - a fleeting moment of recognition, and of choice can occur.
