After being ousted from the Sheriff's Department, Keith Mars opens Mars Investigations, a PI agency, Veronica gains an after-school job as his secretary. Though she is often forbidden from handling certain cases, she often oversteps her boundaries and sometimes even completely solves the case before her father. She is also an unofficial private investigator for Neptune High tracking down computer hackers, digging up dirt on parents, finding out who stole the school's mascot, and the like. She keeps one step ahead of her father and Vice-Principal Van Clemmons through the occasional help of her best friend Wallace — Watson to her Holmes — and classmate Eli "Weevil" Navarro, the leader of the PCH Biker Gang.
