Knife Trouble Erupts on Deadliest Catch Season 21 – Here’s What Happened
A knife incident plunges the Northwestern into chaos.
“Deadliest Catch” is returning for the 4th episode of its 21st season on the Discovery Channel, and it’s set to debut on Friday, Aug. 22 at 8 p.m. You can watch live as it airs three ways: Sling TV, Philo (FREE trial) or DIRECTV (FREE trial).
In the 4th episode of this season, Sig will find himself in an increasingly chaotic situation aboard the Northwestern in the aftermath of an incident involving a knife, while, aboard The Confidence, a crew member will quit causing a different kind of chaos there.

“Deadliest Catch” has, over its long run, become an iconic staple of the Discovery Channel roster. The series depicts the seemingly insurmountable struggles of fishing for Alaskan king crab in the Bering Sea, a commercial fishing trade which is sometimes lethal.
Here’s a look at some of the craziest moments in which a crew member fell overboard across the history of “Deadliest Catch,” courtesy of the show’s official YouTube channel:
How to watch “Deadliest Catch” for free
Sling TV is an extremely customizable, affordable option for watching content that airs on Discovery Channel.
Philo is also a cheap, easy, and straightforward way to watch “Deadliest Catch” for free. However, cord cutters might also be drawn to the larger breadth of options provided by DIRECTV.
New episodes of “Deadliest Catch” air on Fridays at 8 p.m. And if you missed last week’s episode, each Friday, the previous episode will air before the new one at 6 p.m.
