Tasked with pursuing a schoolboy suspected of supplying marijuana, a young policeman becomes troubled by the clash between duty and instinct. The struggle he undertakes with his conscience and his superiors provides an intriguing, philosophical allegory; but most delightfully, it’s played with warmth and humour, and an extraordinary investment in the detail of its characters’ lives.

David Chase, creator of “The Sopranos,” has signed on to write, direct and produce his first feature film.

So far, plot details are being kept under wraps, but the film has been  described as original drama.

A source familiar with the deal said the drama will not revisit the world of the Mafia, which provided the basis for “The Sopranos.””He’s been there, done that,” the insider said. “He’s moving on.”

EXTRAs:Chase’s TV career as a writer, producer and director spans three decades and includes “The Rockford Files,” “I’ll Fly Away” and “Northern Exposure,” as well as the telepic “Off the Minnesota Strip.”
