The Spy Kids series consists of four American/Spanish family action films written and directed by Robert Rodriguez. The main plot follows the adventures of two Cortez children (portrayed by Alexa Vega and Daryl Sabara) who become involved in their parents' espionage. The rest of their family are also spies as well, including their estranged uncle Machete and maternal grandparents. The films tend to have a strong Hispanic heritage theme, as Rodriguez is of Mexican descent.
Ten years before the first film, there was a period of enormous political turmoil. Fearless agents were recruited for espionage missions against enemy spies. Gregorio Cortez and Ingrid Avellan (Antonio Banderas and Carla Gugino) were enemy spies assigned to kill each other, but instead they fell in love and married. After an atypical wedding, Gregorio and Ingrid took a break from espionage and started a family.
