Veronica Mars (2004 - 2019)

While trying to navigate the everyday drama of high school, the smart, fearless, 17-year-old Veronica Mars also moonlights as an apprentice private investigator out to solve her wealthy town of Neptune's toughest mysteries. After coming to the aid of the new kid, sophomore Wallace Fennel, who's been duct-taped to the school's flagpole, Veronica ends up incurring the wrath of the thugs who put him there, Eli "Weevil" Navarro and his P.C.H. Biker Boyz. To get Weevil and his gang off her and Wallace's case, Veronica devises an intricate plan that helps some of Weevil's cronies avoid trouble with the law. Meanwhile, defying her father, Keith Mars, the disgraced former sheriff turned private eye, Veronica pursues a late-night case of adultery against billionaire Jake Kane, only to make an unsettling discovery about her mother, who abandoned Veronica and Keith a year ago.

Veronica doesn't believe the evidence adds up against Weevil, who has confessed to stealing credit card applications from Logan's family, and launches an investigation to help her new ally.

Veronica tries to help her new boyfriend Troy find his father's stolen car and turns to Weevil for assistance, but the situation becomes dangerous when she discovers that Logan and Troy's buddy Luke might have left more than a piata in the car after their night out in Tijuana.
