After losing her long-time acting gig on the hit show Murder 101, Sydney Ryan decides she needs a break from Hollywood politics. She heads to Treasure Island, Florida where her grandmother has been visiting and now refuses to leave. Sydney's plan to lie low for a bit quickly goes awry though, as she is swept up in her grandmother's now flourishing social life--Grand not only bought a new house in Casas de Flores, she's also helping her neighbor Myra open a bookstore in Pass-a-Grille. But when someone breaks into Grand's house repeatedly Sydney realizes her grandmother is keeping something from her.

Determined to ferret out the truth and protect her grandmother, Sydney enlists the help of the Ten Beach Road ladies and Luke, a local police officer who was once her high school crush. While Sydney puts her television crime-solving skills to the test, she decides to act on the sizzling chemistry between herself and Luke. And as Sydney spends more sunsets toasting to true friends and new romance, she begins to wonder if the sun is setting on her time in Hollywood and if this town could be the dawn of a new chapter.
