Merry Wrath's hometown of Who’s There, Iowa may be a nice, if quirky, place to live, but it’s also the murder capital of Iowa—a fact that’s somewhat known only regionally. But all that’s about to change, when a film crew with murder on its mind arrives in town to make a documentary. The team aren’t killers themselves, but they are a bit too eager that a death will happen around the murder-adjacent, ex-CIA agent turned Girl Scout Leader, Merry.
Only when a dead body finally does show up, Merry can’t get anyone in town to believe the man didn’t die of natural causes. It doesn’t help that the documentary’s focus on Detective Rex Ferguson’s 100% solve rate changes when a rumor starts that a major streaming studio is interested. Then every kook in town wants in on the action, and the film crew starts looking into some very fictional reenactments that include explosives.
Things get worse when an anonymous family member of the victim shows up to claim the body for immediate cremation, and Merry realizes that she’s running out of time to solve a murder...before everything blows up in her face.
