Well, without more context, it's hard to say precisely. But generally, a 'true story' about 'champions' might revolve around individuals or groups who have triumphed in the face of challenges. Maybe it details their journey, the setbacks they faced, and how they managed to come out on top. For example, it could be about a team that was underestimated but managed to win a championship through teamwork and determination.
Since we don't have much information, 'champions a true story' might be about people who have become champions in their own right. It could be a story of underdogs who fought against all odds. It might include their personal stories, the training they endured, the support they got from family and friends, and how they became the best in what they do. It could also be about how they inspired others and left a mark in their respective fields.
