When does Charlie's Angels return?

Charlie's Angels is an American crime drama television series that aired on ABC from September 22, 1976, to June 24, 1981. It follows the crime-fighting adventures of three women working at a private detective agency in Los Angeles, California. Kate Jackson, Farrah Fawcett, Jaclyn Smith, Cheryl Ladd, Shelley Hack and Tanya Roberts were the original co-stars. John Forsythe played the unseen Charlie Townsend, who directed the crime fighting operations of the "Angels" over a speakerphone. Despite mixed reviews, the series enjoyed great popularity with audiences.
In the initial concept, Sabrina Duncan, Jill Munroe, and Kelly Garrett have graduated from the police academy in Los Angeles, California. Despite proving their capability during training, all three have subsequently been assigned to be a meter maid, office worker, and crossing guard. Dissatisfied with these jobs, they are recruited to work for the Charles Townsend Agency as private investigators. Their boss, Charlie Townsend, who nicknames them "Angels", is never viewed full-face, but is often seen from the back.
