The hit CBS sci-fi thriller series "Extant" might have gotten a good news turnaround on the last episode, but that does not mean that your favorite characters are out of the woods just yet. The next episode is titled "Zugzwang" and will air on CBS next Wednesday, Sept. 2 at 10 p.m. EDT, according to TV Guide.

As fans of the show already know, Molly is alive and well. To make matters even better for the lead character and her son, they were happily reunited and she got even closer to JD.

But now, there is even more on the line as the trio head out to find the answers and keys to stopping the main threat. According to Spoilers Guide, they pursue a lead Molly has from one of John's old friends.

The old friend will actually come in the form of a mysterious colleague of John's. They believe that he alone holds the key to stopping the growing threat that is the Humanichs. But tracking him down may prove to be the real challenge in this episode.

The story will also invest itself into Julie's affairs. Lucy is now taking orders from a higher command and she needs to know who that is. Lucy did not disclose that information to her, and she needs the answers ASAP. That is where she enlists Charlie to go on a mission to find out for her.

What fans already know is that Molly, JD and Ethan escaped the facility before the explosion and hid out in a bunker, which kept them alive and hidden from the authorities. The bomb was blamed on them and characterized as a terrorist attack.

It also seems as though Toby is playing a double agent and helping them to stay alive.
