SISU follows a ten particular person biking workforce from a small neighborhood in Maine on a journey to compete in a 1,358KM race across the perimeter of Iceland. The one hour documentary combines an observational filmmaking model with components of a travelogue and engagement of motion sport. Set simply after the summer time solstice, the workforce faces quickly altering street and climate circumstances as they push ahead in opposition to the 72 hour time restrict. The movie explores the motivations of beginner athletes pursuing a large bodily problem and considers the position journey performs in up to date life.
