Years after his squad was ambushed during the Gulf War, Major Ben Marco finds himself having terrible nightmares. He begins to doubt that his fellow squad-mate Sergeant Raymond Shaw, now a vice-presidential candidate, is the hero he remembers him being. As Marco’s doubts deepen, Shaw’s political power grows, and, when Marco finds a mysterious implant embedded in his back, the memory of what really happened begins to return.

The series is set in the fictional town of Neptune, California, and stars Kristen Bell as the title character, a student who progresses from high school to college while moonlighting as a private investigator under the tutelage of her detective father. In each episode, Veronica solves a different stand-alone case while working to solve a more complex mystery. The first two seasons of the series each had a season-long mystery arc, introduced in the first episode of the season and solved in the season finale. The third season took a different format, focusing on smaller mystery arcs that would last the course of several episodes.
