Manhunt: Boston Bombers

In April 2013, chaos erupted in Boston near the finish line of one of the world's oldest and most prestigious marathons. It was the worst terrorist attack on the United States since 9/11 and led to one of the most extensive and public manhunts in American history. Now, as the one-year anniversary approaches, National Geographic Channel presents a special two-hour event, Inside the Hunt for the Boston Bombers.

The history of the Boston Marathon from its humble origins starting with only 15 runners, to the first female runners, through the tragedy in 2013, and ultimately the triumph of 2014.

In 1980 Jay Helgerson shocked the world, becoming the first person to run a marathon a week for a year – each race completed in under three hours. For the last ten years, his daughter, filmmaker Alexandra Helgerson, followed him with a camera in order to understand the eccentric man who raised her. What she gets are his projected anxieties, his struggles with physical age and emotional distress, all while he endlessly trains for the Boston Marathon. But as Jay trains, the film is nearly derailed by Alexandra’s encounter with a life threatening illness. Ultimately, AGE GROUP WINNER is an affirmation of the will to live.

This Canadian made comedy/drama, set in Hamilton, Ontario in 1954, is a sweet and - at times - goofy story that becomes increasingly poignant as the minutes tick by. It's the fictional tale of a wayward 9th grader, Ralph (Adam Butcher), who is secretly living on his own while his widowed, hospitalized mother remains immersed in a coma. Frequently in trouble with Father Fitzpatrick (Gordon Pinsent), the principal of his all-boys, Catholic school, Ralph is considered something of a joke among peers until he decides to pull off a miracle that could save his mother, i.e., winning the Boston Marathon. Coached by a younger priest and former runner, Father Hibbert (Campbell Scott), whose cynicism has been lifted by the boy's pure hope, Ralph applies himself to his unlikely mission, fending off naysayers and getting help along a very challenging path from sundry allies and friends.
