The annual Duluth marathon is underway and right at the end of the race, BOOM goes a bomb. The city is set off in a rage after a very public figure incites vigilantism against the Muslims that she deems responsible for the bombing with no proof or reasoning. Protected by the 1st amendment she continues to spew her rhetoric on twitter along with her followers and pretty soon Stride, Maggie, Serena, & the FBI have more crime on their hands as they struggle to piece together the bombing, potential suspects, peace between the Muslim population that has nothing to do with the bombing, & an unstable FBI agent. Too many suspects, trying to stay ahead of false internet information, & more murders spurs the investigation in too many directions. Stride has a different viewpoint on who is really responsible, Maggie ties up too many coincidences, & Serena pieces together other leads. All while the city is on edge and people are taking the law into their own hands, Stride keeps a level head to get to the bottom of the smokescreens to nab the real bomber.
