Former childhood star and die-hard romantic Millie is bound for Key West from Washington DC, determined to fulfil a promise to her elderly best friend, Mrs Nash, by reuniting her ashes with her long-lost love. And if this grand gesture also happens to reassure a recently heartbroken Millie that believing in love isn’t foolish, all for the better.

When flights are grounded, Millie is forced to catch a ride with Hollis, an also-stranded near-stranger from her ex’s grad school. Hollis, a rising literary star, doesn’t believe in forever-loves (or even for-now loves). He was headed to Miami for a no-strings-attached hook-up, in the hope of curing his writer’s block.

But as Millie and Hollis make their way across country, racing down open highways and staying in questionable hotels, will their trip turn into a love story all their own?
