Slender and attractive blonde Monica Zanchi was born in Bern, Kanton Bern, Switzerland. Zanchi lived the first seven years of her life in Bern before moving with her family to Bergamo, Italy to treat her ailing brother. Monica's family decided to settle in Italy, so she studied in Bergamo for a while prior to deciding at age fifteen to leave home without informing her parents to hitchhike abroad alone. For a whole year her family didn't know her whereabouts, to the point where the Interpol was notified of her absence, until they started receiving bills from various hotels where she ran a scheme of checking in pretending that her parents are "on their way", and then sneak out without paying rent after a couple of weeks of stay. Zanchi found herself traveling to such places as Spain, France and England. Later, Monica hitchhiked to Sicily. While in Sicily, she met a movie agent who convinced her to have some still shots taken of her. Monica subsequently embarked on a brief acting career in various Italian exploitation pictures.
