Digicorp's Head of Security, Finster [Nigel Bennett], inducts Morgan, and assigns him a new identity. As Jack Thursby, he is sent to conventions to secretly record presentations and transmit them to headquarters. Sullivan is soon haunted by recurring nightmares and neck pain. When he meets Rita Foster (Liu) from a competing corporation, his life starts to become complicated...Morgan discovers that all the convention attendees are spies like him, and all thinking themselves individual spies working for Digicorp. While they are drugged from the served drinks, plastic-clad scientists probe, inject and brainwash them. Individual headsets reinforce their new identities, preparing them to be used, and then disposed of. Morgan manages to convince Digicorp that he believes his new identity. He is then recruited by Sunway Systems, a rival of Digicorp. Sunway's Head of Security, Callaway [Timothy Webber], encourages Morgan to act as a double agent, feeding corrupted data to Digicorp. Morgan calls Rita, who warns him that Sunway are equally ruthless, and that he is in fact being used by Rita's boss, Sebastian Rooks. Morgan manages to steal the required information from Sunway Systems' vault, escaping with Rita's help," informs Wikipedia plot summary.
