The Game Plan tells the story of rugged superstar quarterback Joe Kingman (Dwayne "The Rock" Johnson), whose Boston-based team is chasing a championship. A "serial bachelor," Kingman is living the ultimate fantasy: he's rich, famous, and the life of the party. But this dream is suddenly sacked when he discovers the 7-year-old daughter (newcomer Madison Pettis) he never knew he had. Now, during the most important time in his career, he must figure out how to juggle his parties, practices, and dates with the newfound ballet classes, bedtime stories, and dolls that come with his daughter. Equally perplexed is his hard-edged mega-agent Stella (Kyra Sedgwick). Despite the often hilarious misadventures that come with being a new father, Joe discovers that there's more to life than money, endorsements, and thousands of adoring fans - the love and care of one very special small fan.
