Keira Malone raised her three children alone after her first marriage broke apart. After years of guarding her heart she finally finds love again. But that love is short-lived when her fiance suffers a fatal heart attack.

Not wanting to live underfoot, she rents a charming cottage, replete with views of the ocean and her neighbor's thriving garden, not to mention views of the neighbor himself.

But things get real when Bryan's long-lost daughter, whom he hasn't seen since she was a baby, shows up out of the blue, resulting in Bryan and Keira each delving into their pasts, and reopening old wounds.
