In a sleepy New England town, a letter has arrived that is sure to wake things up. It's a love letter - ardent, sensual... and unsigned. As the letter falls into different hands, residents of the small town start to eye one another with renewed interest - wondering who it's for, and who it's from.

Determined to find the letter's author, Helen MacFarquhar (Kate Capshaw) begins a quest that will open her life to a new chapter involving two decidedly different men: George (Tom Selleck), an old friend from her past, and Johnny (Tom Everett Scott), a young man very much in her present. Unexpectedly, one mysterious love note has the power to unlock some startling secrets, leaving a trail of wonderful surprises as it turns the entire town upside down.
