Private Detective Doyle Malloy is on the case when a string of murders pop up in North Dakota. Murders that have a striking similarity to a killer from the 1980s who used pickles—yes, pickles—as his modus operandi. A killer who also has a mysterious connection to Doyle's own past. After witnessing a murder on-stage at the Fitzgerald Theatre, Doyle begins to wonder if some of the odd coincidences surrounding his investigations aren't so coincidental after all. Doyle and his team of misfit detectives embark from the Twin Cities to the prairies of North Dakota on a dangerous road trip they won't soon forget.
