Diamonds of Béisbol follows the Académie de Baseball du Canada (ABC), a determined group of female baseball players from Trois-Rivières, Québec. As they strive to qualify for the national championships in Halifax, Nova Scotia, the team travels to Havana, Cuba, where they train and compete alongside the Cuban women’s national team in a unique cross-cultural exchange. Facing language barriers, social differences, and on-field tensions, the athletes ultimately discover that mutual respect between Canada and Cuba can help them push past challenges and pursue their dreams.
