It’s time to bring out the silver bombs. FX announced the premiere date of the fourth and final season of “The Strain.” Season 4 kicks off on Sunday, July 16 at 10 p.m. EDT.

When “The Strain” returns, nine months would have passed since the events of Season 3. According to the official synopsis, the world has fallen into darkness and the strigoi are in control. The explosion at the end of the Season 3 finale, which was triggered by Dr. Ephraim “Eph” Goodweather (Corey Stoll) son’s Zach (Max Charles) resulted in a global nuclear explosion (that was not just confined to New York).

The resulting nuclear winter has liberated the vampires and they can now move freely during the daytime. This allowed The Master, who has now occupied Stoneheart CEO Eldritch Palmer’s (Jonathan Hyde) body, to establish a totalitarian regime.

The synopsis also reveals that The Master and his minions have made an unsettling alliance with humans referred to as The Partnership. Using fear as a powerful tool to control humans, they have surrendered and are working for the strigoi. They have realized that they must either collaborate with the vampires or face death.

All the major characters in “The Strain” are disbanded in Season 4. Each of them will have to overcome their own personal hardships and defy death if they want to fight back.

Furthermore, with The Master now ruling the world, the end of the world is much closer than humans believed.

At the end of Season 3, not only did Zach trigger a nuclear explosion, but Eph, Setrakian (David Bradley), Fet (Kevin Durand) and Dutch’s (Ruta Gedmintas) plan to drown The Master in the ocean in a casket made of silver failed miserably. It was a good plan which ensured that The Master could not communicate with his vampires and he would not be able to release himself from the coffin.

Unfortunately, Zach’s explosion derailed the plan.

Even worse, while trying to escape the city for good, Gus (Miguel Gomez), Angel (Joaquín Cosio), Justine Feraldo (Samantha Mathis) and her right-hand man Frank (Paulino Nunes) were attacked by a horde of strigoi. The ensuing fight resulted in Feraldo, Frank and Angel’s death. RIP Angel!

Although “The Strain” Season 4 begins on a gloomy note, it is the final season of the FX horror series. Which means, somehow, The Master will be defeated. However, the strigoi-hunters are now faced with their biggest setback so the group’s morale is at an all-time low.

There is increasing speculation that The Master will groom Zach to be his new vessel after Palmer’s body outlives its use. This is because, first, the strigoi leader is very fond of Zach and his penchant for darkness, and, second, in the books, Eph’s son is groomed to take over The Master’s body.

“The Strain” is based on a best-selling trilogy written by Guillermo del Toro and Chuck Hogan. Both writers also serve as co-creators and executive producers on the TV show.

The series also stars Richard Sammel as The Master’s Nazi-loving lap dog and right-hand man, Thomas Eichorst, and Rupert Penry-Jones as The Master’s son (a half-human-half-strigoi) Quinlan.

“The Strain” Season 4 premieres Sunday, July 16 at 10 p.m. EDT on FX.
