Lana Lewis is brewing up new concoctions at Perkatory, a popular café in Devil's Beach, when she decides she wants to try her hand at growing her own coffee. She secures a gardening plot in the community garden, thanks to her father and the garden's owner, Darla. Darla's list of rules is long, but that doesn't stop someone from leaving Jack Daggett's body amongst the gardening plots.

Jack, an environmental activist, had been banned from the garden previously, because of his many fights with Darla about organic produce. Lana promises her boyfriend, police chief Noah, that she's going to stay out of this case, having been too involved in previous cases. But when she learns that Jack died from an accidental overdose, and Darla is the top suspect because of her shady past, Lana can't help but poke around in an attempt to clear Darla's name.

As Lana dives deeper into the case, she learns that Jack had more enemies than she realized. When Darla turns up dead, Lana has to turn up the heat on her investigation. With Lana on the case, it won't be long before someone spills the beans to crack this case wide open. But will she able to find the killer before they strike again?
