Mr Robot recruits Rami Malek's Elliot Alderson, a cybersecurity engineer and hacker who suffers from anxiety and clinical depression.

Following on from the dramatic season-two finale, the new series will follow the disintegration of the relationship between Elliot and Mr. Robot. It will air in October.

The show was created by Sam Esmail, and has influences as disparate as American Psycho, Taxi Driver, A Clockwork Orange and The Matrix.

The show has been lavished with acclaim, and has won multiple awards, including the Golden Globe for Best Television Drama Series and Peabody Award.
