Welby's third short film Sparrow is a beautiful, non-spoken 15-minute story set in the 1960's, and is told from the perspective of Jim, a small boy who believes he can fly. Jim's life is overshadowed by a story about his grandfather who died a hero in World War 2, but he discovers that the legend that his father so adamantly clings to, is a lie.

In unraveling the truth behind what happened, Jim discovers strength in his grandfather's actions and stands up to the bullies at his school in an unexpected way.
