Plot
Professional football Mike Hanson plays for The Whalers, but gets seriously injured shortly after recovery from another injury, so must go onto the injured reserve. Nursing broken ribs, he returns to his hometown to his brother Jimmy's. While there, Mike is convinced to assistant coach his niece Zoey's all-girl flag football team.
Single mother real estate agent Erin Allen's 12-year-old daughter Kira plays in the flag football league. One day, while sharing the field with another team during practice, Kira notices the all-girl flag football team. As her male teammates refuse to pass to her, she convinces Erin to help her join it.
When Erin asks coach Jimmy to let her daughter join, she realizes her ex Mike, the college boyfriend she broke up with, is assistant coaching the all-girl team. Initially, they act awkwardly, but she watches him to ensure he does not put strain on his healing rib cage. Erin tells her real estate partner Georgina about seeing her ex, admitting she had broken his heart.
Meanwhile, Jimmy and his wife Danielle pump Mike for details, which he insists there are none. Later, at the Whalers flag-football team's fundraiser, the coordinator is surprised that both Danielle and Erin offer to approach the football star for help, unaware of their connection to him.
Afterwards, the former introduces herself to the latter, explaining she is his sister-in-law. Erin says he is a college friend. Danielle invites her to a barbecue that night at the Hansons.
When Erin and Kira arrive, Mike gets visibly nervous. Jimmy and Danielle find an excuse to leave them alone. Soon after, Grandma Gertie and her boyfriend appear and are also encouraged to leave Erin and Mike alone.
Erin and Mike talk about where their lives have taken them until now. He is preoccupied about his future on his football team, due to the back-to-back injuries. Erin explains she became a full-time housewife when her daughter was born, then her husband left her. So she and Georgina started their real estate business.
Attempting to talk about their college break up, Mike is obviously still upset and Erin will not explain herself. So, she suggests they keep their distance while he is here. They enter the house to tell Jimmy and Danielle.
Jimmy reveals the high school has offered him an assistant coach job, which he plans to take. However, he is concerned about the middle school flag football team. Erin and Mike talk privately and ultimately agree to try to be friends for the team's sake.
Erin, with her kinesiology degree, constantly watches that Mike not hurt himself. After practice, as Jimmy and Danielle cannot get him, she and Kira give him a ride. Since they are having lasagna, Kira convinces Erin to invite Mike.
As Erin and Mike spend time together again, their romantic past feelings resurface. With Kira on a sleepover with her team, Mike invites the free Erin to a charity event at the local nursing home. They have a nice time, so the next day she is distracted at work, prompting Georgina to suggest she might be in love.
The girls' team reaches the final. As they start to play, Mike's manager Richard appears, saying he has been reinstated on the team, so must leave immediately to prepare to play the next day. Richard approaches Erin, complaining that she is distracting him from what is important, to hurry back to work. She reminds him he had already convinced her to walk away from Mike once, insisting it was his best option to be drafted.
As Michael leaves with Richard, he realizes he has blocked his relationship with Erin twice. By phone, he proposes a game winning play to the flag team. Mike is reinstated on his team and in the last play, just as with the flag football team, he suggests they do a fake to win.
After the game, Richard criticizes Mike for not scoring the last goal. Mike reveals the team manager offered him to stay through the end of his career with a pay adjustment, which he accepted. Richard protests, so he states he is no longer his agent effective immediately.
Erin appears at the stadium, announcing she will be with him, regardless of his team. Mike happily informs her he will stay, finishing his career with the Whalers. They mutually declare their love, then kiss.
