Trying to evade the matchmaking efforts of their grandmothers, two former childhood sweethearts pretend to get back together for the summer.

English teacher Penelope Campbell loves her annual summer vacations visiting her Grandma Dot, despite Dot's constant attempts to set her up with every single man in town. This year, she bumps into Jason Humphrey, none other than her childhood sweetheart, who is still as handsome and charming as ever. It's a little awkward at first, but the conversation soon turns to Jason's own Grandma Josie, who keeps doing the same to him. In order to evade the efforts of their matchmaking grandmothers, they make a pact pretending to date each other, but will the old sparks return?—Reel One Entertainment

Having then dated but not seen each other since high school, middle school teacher Penelope Campbell and investment banker Jason Humphrey are staying with their respective grandmothers for the summer. Grandmas Dot and Josie are not only friends but lakeside next door neighbors. Pen's visit is largely for Dot's milestone 75th birthday celebration, while Jason, at a crossroads in his life, wanted an escape to a place with happier memories. Outwardly, it seems like Dot and Josie's respective missions this summer are to find a boyfriend/girlfriend for Pen/Jason, they setting the two up on one "accidental" meeting with the opposite sex after another, including with each other. Neither Pen or Jason are in any position for a relationship this summer, let alone with each other, especially as there are still some hurt feelings from that time in high school. Not wanting to tell anyone just yet, Pen has to make changes to her novel manuscript - this her first - her editor Liam having gotten her a conditional publication deal on those changes being approved, after a series of rejections from other publishers. In addition to the imminent publisher set deadlines, Pen wants to have the final changes approved - if they are ever approved - by Dot's birthday. And one of the issues that Jason is currently dealing with is an emotionally difficult break-up. As such, Jason comes up with a plan that Pen eventually agrees with to get their grandmothers to stop setting them up: they should "fake" date for the summer, their time together allowing Pen to make the changes to her manuscript, and Jason to embark on his major summer project of fixing up Josie's broken sailboat. What Pen and Jason don't know is that they are playing exactly into what Dot and Josie had planned, the wanted outcome if Pen and Jason will allow themselves to open up and not make what may be incorrect assumptions of what is best for the other.—Huggo
