Elliot Alderson is a young cyber-security engineer at Allsafe Cybersecurity in New York City; However, in his free time he's a vigilante hacker. He is recruited by fsociety, a group of black hat hackers led by Mr. Robot, to help take down a large corporate conglomerate, E Corp. E Corp is Allsafe's biggest client as well as responsible for the death of Elliot's father, putting him in a place of divided loyalties.

In MR. ROBOT, Elliot, a cyber-security engineer by day and vigilante hacker by night, is recruited by a mysterious underground group to destroy the firm he's paid to protect. Elliot must decide how far he'll go to expose the forces he believes are running (and ruining) the world.

Tyrell Wellick, now Evil Corp's acting CTO since Elliot helped get Terry Colby arrested, makes Elliot an offer he can (and does) refuse: a position as Evil Corp's head of Cyber Security and a big bank account to match. By saying no, has Elliot made himself a mark for Wellick?

After being shoved off the railing in Coney Island by Mr. Robot, Elliot wakes up in a hospital room, badly banged up. Krista, his psychiatrist, is inclined to send him to rehab unless he's willing to be regularly drug tested. Elliot complies, knowing that he can easily change the hospital records for the tests since he hacked their system long ago.

At fsociety, Elliot lays out his plan to hack Steel Mountain's climate control system and raise the heat high enough to melt all the tapes that record the data. Romero points out the plan's many flaws but when Elliot remembers that they only have a few days left before Evil Corp switches over to their new redundant security protocols based on what Tyrell Wellick told him, they reluctantly agree it's now or never.

Fsociety attempts to penetrate Steel Mountain, the most secure data facility in America.

Elliot attempts to hack Vera out of jail in order to save someone he cares about; Tyrell's "game" gets crazy; and Angela digs deeper into her mother's death.

Elliott goes missing; Mr. Robot tries to pull fsociety back together; Angela goes head-to-head with an old nemesis.

Allsafe is controlled; the Dark Army is ready to meet Elliot; and Tyrell and Joanna's plan goes into effect.

The Evil Corp hack is threatened by a mystery man from Elliot's past.

In the Season 1 finale, Mr. Robot and Tyrell are MIA; and a past hack haunts Elliot.
