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 his broken ribs, Mike returns to his hometown to stay at 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 mostly-male teammates refuse to pass to her, she convinces to let her join it.
When Erin asks the coach to let her daughter join, she realizes that Mike, her ex, college boyfriend that she broke up with, is assistant coaching the all-girl team. Initially, they act awkwardly, but she keeps an eye on 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 ended their relationship, which he says broke 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 she is a college friend. She gets invited 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 show up 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 as to what his future will be on his football team, fearing that they might let him go because of the back-to-back injuries. Erin explains that when her daughter was born she became a full-time housewife, but then her husband left her. So she and Georginastarted 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 she say far from him while he is here. They enter the house to tell Jimmy and Danielle.
However, the Middle School flag football team gets bad news. Jimmy gets offered an assistant coach job at the high school. Planning on taking it, Jimmy is concerned about the flag football team. Erin and Mike talk privately and ultimately agree to try to be friends for the sake of the team.
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. As they are having lasagna, Kira convinces Erin to invite Mike.
As Erin and Mike spend time together again, their romantic past begins to 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. Just as they start to play, Mike's manager Richard comes to inform him that he has been reinstated on the team and must leave immediately to prepare to play the next day. Richard approaches Erin, complaining that she is distracting him from what is important, which to him is hurrying 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 he discovered the team manager had offered he could stay through the end of his career with a pay adjustment, which he accepted. When Richard protests, 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 is staying, finishing his career with the Whalers. They mutually declare their love, sealing it with a kiss.
