Chance at Romance (2014) on Netflix

Plot summary

Blind dates have worn Samantha Hart down, and a photography exhibition introduces her to the work of Heath Madsen. Her email to him lands in the home he shares with his twelve-year-old son, Donny, who reads it before his father does. Donny wants a match for his widowed father and dreads the blonde manager who might become his stepmother, so he replies as Heath and invites Samantha to visit, first-class ticket included. Samantha arrives expecting a romantic weekend and finds the correspondence was the work of a boy. A spell of bad weather stretches her stay to the end of the week.
