"Gaslit" is a modern take on Watergate that focuses on the untold stories and forgotten characters of the scandal – from Nixon's bumbling and opportunistic subordinates to the deranged zealots aiding and abetting their crimes to the tragic whistleblowers who would eventually bring the whole rotten enterprise crashing down.

The story will center on Martha Mitchell, played by Julia Roberts. A big personality with an even bigger mouth. Martha is a celebrity Arkansan socialite and wife to Nixon's loyal Attorney General, John Mitchell, played by Sean Penn. Despite her party affiliation, she's the first person to publicly sound the alarm on Nixon's involvement in Watergate, causing both the Presidency and her personal life to unravel.
