In the wealthy, seaside community of Neptune, the rich and powerful make the rules. They own the town and the high school, and desperately try to keep their dirty little secrets just that - secret.
Unfortunately for them, there's Veronica Mars, a smart, fearless 18-year-old apprentice private investigator dedicated to solving the town's toughest mysteries.
During the day, high-school senior Veronica must negotiate the halls of Neptune High like any average teenage girl, alongside her friends Wallace Fennel and P.C.H. Bike Club leader Eli "Weevil" Navarro.
By night, Veronica helps with her father Keith's private investigator business, sneaking through back alleys and scoping out no-tell motels with a telescopic-lens camera and her math book in an attempt to uncover the California beach town's darkest secrets.
And in between, Veronica frequently helps add to her college fund by tackling a variety of problems for desperate classmates.
Veronica's father was the sheriff, until he accused Veronica's best friend of killing his daughter, Lilly. Veronica then lost her boyfriend and popularity, when she became an outcast in her home town, due to the events after her best friends murder.
While she assists her father, she is still trying to uncover the truth as to who murdered Lilly Kane.
