This first season of the series begins as Sydney begins work as a double agent for the CIA, who want to destroy the organisation and its leader, Arvin Sloane. Sent all over the world on various undercover missions, Sydney must sabotage SD-6's efforts while maintaining her cover so that she can help take down SD-6 from the inside. Quite possibly the most entertaining show to debut on television in the last decade, ALIAS is a fast-paced thrill ride buoyed by Ms. Garner's performance as well as her penchant for wearing some outrageously risque disguises on her missions.
