The TV Cave’s Daily TV Guide: What to Watch on April 21

If your watchlist is looking a little dry, don’t worry—tonight’s TV lineup is doing the absolute most. From buzzy streaming debuts to high-stakes playoff action and a whole lot of drama (both scripted and very, very real), there’s something worth flipping on at pretty much every hour.

Let’s break down what deserves your attention today 👇

🌙 Late-Night Streaming Drops (3:00 AM ET)

Netflix is clearly not here to let you sleep.

Unchosen (Series Premiere) A twisty new drama arrives with a full six-episode binge drop. It follows a young mother escaping a restrictive cult who gets pulled into a dangerous relationship that unlocks long-buried secrets. Expect obsession, tension, and the kind of slow-burn chaos that keeps you clicking “next episode.”

Untold: The Shooting at Hawthorne Hill Another gripping entry in the Untold documentary series dives into a shocking dispute that spirals into violence—and a courtroom twist you won’t see coming. True crime fans, clear your schedule.

🏀 Primetime Sports Takeover (7:00 PM ET)

NBA Playoffs The postseason rolls on with a stacked lineup:

• Philadelphia 76ers vs. Boston Celtics

• Portland Trail Blazers vs. San Antonio Spurs

• Houston Rockets vs. Los Angeles Lakers

If you’re in the mood for buzzer-beaters, rivalries, and last-minute drama, this is your lane tonight.

🌾 Reality, Crime & Drama Collide (8:00 PM ET)

Farmer Wants a Wife (Season 4 Premiere) Love is back in the countryside as three farmers meet 27 hopeful singles. Expect awkward first impressions, instant connections, and some tough cuts as farm life meets dating chaos.

NCIS With the team mostly gone and systems offline, a small crew is trapped inside headquarters with a threat lurking within. It’s a locked-down episode with serious tension—and a familiar face stepping up.

Summer House Emotions run high as relationships are put under the microscope and personal struggles come to the surface. Not exactly a chill summer vibe.

Will Trent The search intensifies as the team closes in on dangerous targets, while Will battles grief that could derail everything. This one leans heavy.

🔥 Peak Drama Hour (9:00 PM ET)

Daredevil: Born Again No official details, but let’s be real—you already know this is appointment viewing.

NCIS: Origins A case brings Gibbs and Lala closer, but family complications threaten to shake things up in a big way. Personal and professional lines blur fast.

R.J. Decker Big decisions and buried family secrets take center stage as the pressure builds across multiple fronts.

Running Wild With Bear Grylls (Season 9 Premiere) Matthew McConaughey joins Bear for a rugged adventure through Norway’s icy wilderness. It’s equal parts breathtaking and “why would anyone do this voluntarily?”

🚨 Late-Night Stakes (10:00 PM ET)

NCIS: Sydney A hostage crisis in a hospital forces the team into an impossible moral dilemma. Expect high tension and tough choices with no easy answers.
