Sick from the same adulterated vaccine that has been killing refugees, Michael seeks help from Professor Cooper (Paul Higgins), a microbiologist. Sent to retrieve blood samples from other victims, Stephen has a startling revelation.

Reunited with Michael, who is back from the dead, Stephen and Yasim agree to help him find the truth about a mysteriously contaminated hepatitis B vaccine. Stephen ends up stripped of his identity and homeless.

Stephen and Yasim join forces with rogue agent Russell to get to the bottom of a bio-weapons conspiracy that may be connected to a government surveillance program called Total Information Awareness (TIA).

Noted microbiologists are dying at an alarming rate as Stephen tries to learn the cause of death of the beautiful woman found in his apartment. Yasim suspects that her late husband, Michael, stumbled on the secret before being blown up by a landmine in Afghanistan.

Returning to England for his brother's funeral, Stephen Ezard falls in love with his brother's widow, Yasim, becomes a pawn in a government surveillance scheme, and is pursued by a crazed rogue agent.
