It's summer in Wings Falls, New York and Samantha Davies is geared up for the annual trout tournament sponsored by Al Gorman, owner of the Sport's Shop. Sam, along with her Southern Belle cousin, Candie Parker-Hogan, are determined to beat the pants off their significant others, Sam's new fiancé, Hank Johnson, a detective on Wings Falls police force and Mark Hogan, Candie's husband. The ladies feel they have a secret weapon-they learned from the best fisherman in Hainted Hollar Tennessee, Grandpop Parker. Sam once won a trophy for the largest fish in the Fins and Tails Fishing Derby. To Sam's surprise instead of reeling in the day's biggest catch, she "hooked" into the body of the town's most vocal activist, Luna Wheeler. Raylene Carrigan, owner of a traveling doggie daycare Sam uses for her lovable dachshund, Porkchop, becomes a prime suspect, when it becomes known Luna tried to shut down the town's doggie park she depends on for the pets in her care. Since Sam has successfully helped solve murders in the past, Raylene begs her for help to prove her innocent. Sam reluctantly agrees but knows her fiancé won't be happy with her involvement in yet another murder case. Determined to help Porkchop's buddy, Sam starts digging for clues only to discover that Luna, with her over-zealous demands to many of the town's businesses to recycle, upset more than a few of her friends. Can Sam land Luna's murderer before she gets 'hooked' by the killer?
