The Season 2 trailer for Hulu‘s Paradise teases that plenty more secrets are threatening to come to light about both the catastrophe that wiped out much of humanity and the creation of a bunker to save the U.S. President and a handful of others.

The trailer, which debuted Wednesday, features Sterling K. Brown‘s Xavier Collins telling Shailene Woodley‘s newly introduced character about his time underground, uncovering the lies that he’d been told about the world above, and his decision to venture back into what he presumed to be a nuclear wasteland to find his wife. While he’s finally made it out (after crashing the plane he stole into a tree), the trailer makes clear that he’ll face many more obstacles if he intends to make his way to Teri.

It also appears Xavier hasn’t yet uncovered everything there is to know about the place he’s spent the last several years just yet, either, as Thomas Doherty, who also joins in Season 2 as the leader of a biker gang, teases in another clip: “This bunker, there’s something that nobody knows about. Something dangerous.”

Meanwhile, Julianne Nicholson’s Sinatra is facing intense scrutiny back inside the bunker, interrogated about whether she’s “comprising the integrity of the bunker” for her own personal gain.

Watch the trailer above.

The Hulu political thriller series will return with the first three episodes of Season 2 on Monday, February 23.
