Banished for his sins in 1983, Martin wallows in limbo until his Aunt Lenora conscripts him into her plan to drum up hard currency abroad.

Martin reluctantly agrees to help Lenora.

Gary Banks double-crosses Martin and Lenora, leading them headfirst into a proxy conflict at an Angolan oil refinery. Seriously injured in the fighting, Martin is abandoned by Lenora.

Badly injured, Martin wakes up in the Libyan desert, where he meets Samira and Khaled, and uncovers an imminent terrorist plot. Meanwhile, Lenora arrives at an Angolan hotel.

Brigitte tries to convince Martin to work as a double agent.

Lenora returns to East Germany with Rose, determined to develop top-secret communication technology for the ANC in a secret operation called Operation VULA.

Martin has positioned himself for a trade back to East Germany but needs to prove his loyalty to the BND before they accept him as a double agent. Meanwhile, Tina is incarcerated in STASI prison with no idea where her family is.

Martin is finally able to return to the East and see his son for the first time.

Lenora is grounded and demoted after the cruise ship plan is uncovered.
