When she's not piloting a glass bottom boat, showing the sights to tourists, Whit sells seashells by the seashore--among many other sea and sand souvenirs--to help keep her family shop, Nautically Yours, afloat. It's a far cry from her corporate climbing ladder life in Los Angeles, but Whit and her frisky feline, Whiskers, love calling Catalina home and being close to family. Especially Whit's grandmother Goldy, a fun and feisty senior who always marched to the beat of a different drum.

In her youth, Goldy was an item with a Catalina catch named Darren. But it was actually a ruse to fool Darren's parents who wouldn't have accepted his preference for men. Eventually, he left the island and chose the life--and life-partner--he wanted for himself. Back in town for his mother's funeral, Darren takes the opportunity to heal his open wounds, and settle some scores.

In a surprise to the residents, Darren produced a documentary about the history of Catalina, and has arranged a premiere screening in the local theater. But his film career is cut short when his partner's dead body is discovered the night before the opening. Rumors swirl about Darren's past, along with his partner's--and the things they've done--giving a lot of folks a lot of motives. Now, it's up to Whit and her boyfriend policeman to catch a killer, and uncover just how much Grandma Goldy knows about the back door deals tied to Darren's past . . .
