Ethan Dawson, once hailed as the "Arrow God,"lost the World Championship when his bowstring snapped at the decisive moment. After the death of his mentor, Martin Lowell, he retired from archery and disappeared from the sport. Three years later, a down-and-out Ethan is mistaken for a junk collector when he wanders back into the Lowell Archery Club. He reveals his true identity in an unexpected display of skill and is invited by Claire Lowell to stay and coach her brother, Lucas Lowell. Facing Ryan Cole's open disdain and investor Victor Kane's takeover threat, Ethan trained Lucas to win the Arrowheart Cup in a technique called the "Shockwave Shot"and secured a place at the World Championship. At the tournament, Team Lowell battles their longtime rival, the Black Dragon Squad, led by Ethan's old adversary, Jin Park, and overcomes the team's "Phantom Arrow"scheme. In the showdown, Ethan unleashes his ultimate move—the "Phoenix Soul Arrow"—defeating Jin Park, winning the title for his team, and fulfilling his promise to his late mentor.
