Analyzing the files Oscar stole, Alex brilliantly guesses his Black dagger target, MO and purpose, to discredit fracking so as to render Russian gas indispensable to the West by sabotaging a plant. Time runs out, as Oscar already executes his elaborate plan posing as a federal inspector after staging a minor incident and killed all control room staff. The O'Connor family races against time to prevent the fatal explosion last-minute, risking Mark's life. Victor enlists deputy Roman so he can eliminate the Rezident and claim his post. Alex convinces his parents to run as even Sam, who survived, probably can't prevent their arrest, then tracks down Oscar, but faces a brilliant escape plan. .
