“Knowledge comes at a cost.” That foreboding warning sets the theme for the first look at Season 4 of MGM+‘s sci-fi horror series From. The streamer revealed the new season will premiere Sunday, April 19, and unveiled the first trailer which you can watch above.

Created by John Griffin (Crater) From unravels the mystery of a nightmarish town that traps all those who enter.

“If we push too hard, something will push back,” a voiceover is heard in the teaser.

In Season 4, the closer the residents of town get to the answers they seek, the more terrifying their search becomes. There are many questions to be answered. Who is the Man in Yellow, and what does he want? Will Jade and Tabitha’s revelation be the key to finally going home? How much longer can Boyd hold the town together, even as his body and mind are falling apart? And what role will the town’s most recent arrival play in the events to come? Season Four will open doors that some in town will end up wishing had remained closed, according to the official logline.
