Watch Dogs: Legion: - E1 - "DedSec Is Not The Enemy!"
The London Branch of DedSec, led by Sabine Brandt and her newly crafted AI, Bagley, detect armed intruders planting explosives in the Houses of Parliament. DedSec operative Dalton Wolfe goes to defuse the bombs and discovers the intruders to be members of a rogue hacker group called "Zero Day". While Dalton manages to prevent Parliment's destruction, he is swiftly gunned down by drones commanded by Zero Day's leader, who detonates additional explosives around London and orders an attack on DedSec's hideout, forcing Sabine to shut down Bagley and go into hiding. In the wake of the bombings, the British government contract Albion with restoring order to London and hunting down DedSec, who are held responsible for the chaos, effectively causing social and political unrest amongst the city's inhabitants.
Months later, Albion enforces the law without political oversight, transforming the city into a surveillance state with the aid of SIRS ─ a collation of Britain's intelligence agencies. As a result, London's citizens have their personal liberties severely restricted and their lives constantly monitored,[5] and those who question Albion's methods are either arrested or disappear, including those being processed for deportation to Europe. In addition, organised crime is on the rise, despite Albion's presence. Although most DedSec members have been arrested or killed by Albion, Sabine resurfaces when she finds a new recruit through the city's ctOS, assigning them to reactivate the group's safehouse and Bagley. DedSec slowly rebuild their strength as they find more recruits who, under Sabine's co-ordonation and with Bagley's help, liberate various boroughs by encouraging citizens to rise up in defiance of their oppressors.
During this time, DedSec investigate the bombings and soon discover that both Albion CEO Nigel Cass and Clan Kelley's leader, Mary Kelley, were somehow involved, and are taking advantage of London's current situation for their own ends. DedSec is later contacted by Richard Malik, a member of SIRS, who has a lead on Zero Day and presents evidence that SIRS leader Emily Child was responsible for the bombings. However, when Child confronts DedSec, she reveals that Malik's lead was fake and that he wanted to infiltrate the group to supply their identities to Albion. While trying to capture Malik, DedSec are blamed for another bombing that kills Child and allows Malik to take over SIRS. With Bagley's help, the group eventually capture Malik and clear their names, but learn he wasn't behind the Zero Day bombings.
