Martin is ordered by Tischbier to steal a top secret security report.

While at a NATO conference in Brussels, Martin gets his first assignment: to seduce and bug the head security analyst’s secretary, Linda.

When the bug is found in Linda's desk, NATO is placed on high alert. Linda arrives to visit Martin, who scrambles to turn her loyalties around.

Martin is sent back to East Berlin, but is forced to deliver a seemingly harmless package to a mysterious man in West Berlin on the way.

Martin wants to stay in East Germany after returning for his mother’s kidney transplant. Alex Edel takes General Jackson hostage.

As preparations for NATO’s nuclear war game intensify, Martin receives an order from East Germany that cements his fears about their paranoia.
