The Boys season 4: release date, trailer, cast, plot and everything we know about the superhero series

As if things weren't crazy enough in The Boys season 3, things are about to go to a whole new level in The Boys season 4. Prime Video's superhero satire about a group of vigilantes trying to save the world from superheroes who use their powers for nefarious purposes returns, and this season there's lots of family drama to look forward to.

The good news is that The Boys has already been renewed for season 5, so fans can watch the latest season knowing there's more action on the way. The show's first spinoff, Gen V, was renewed for a second season and another spinoff, The Boys: Mexico, is in the works.

Here's what we know about The Boys season 4.

The Boys season 4 release date

The Boys season 4 premieres Thursday, June 13. Three episodes will be released on Prime Video on the premiere day with the rest of the episodes dropping weekly.

The Boys season 4 will be available exclusively on Prime Video, which means you need a subscription to Amazon Prime in order to watch.  With an Amazon Prime account, you'll not only have access to Prime Video and all of the exclusive content available to viewers, including past seasons of The Boys, but you'll also be able to take advantage of all the great deals they offer, too.

The Boys season 4 cast

Most of The Boys cast is returning from season 3. Joining the cast in season 4 are Rosemarie DeWitt (The Estate), Rob Benedict (Supernatural) and Elliot Knight (Call of Duty: Modern Warfare II), along with previously announced newcomers Susan Heyward, Valorie Curry, Cameron Crovetti and The Boys superfan Jeffrey Dean Morgan (The Walking Dead).

DeWitt plays Hughie’s mom, and that will no doubt play a big role in the season 4 storyline. Heyward and Curry will bring Sister Sage and Firecracker to life and Crovetti will play Homelander's son, Ryan. Morgan's role is being kept under tight wrap, but we know it’s a recurring role.

Take a look at the cast members lined up for season 4:

• Karl Urban as Billy Butcher

• Jack Quaid as Hughie Campbell

• Anthony Starr as Homelander

• Laz Alonso as Mother's Milk

• Karen Fukuhara as Kimiko Miyashiro

• Erin Moriarty as Annie January/Starlight

• Tomer Capone as Frenchie

• Jessie T. Usher as A-Train

• Chace Crawford as Kevin Moskowitz/The Deep

• Colby Minifie as Ashley Barrett

• Claudia Doumit as Victoria Neuman

The Boys season 4 plot

Here's the official synopsis of The Boys season 4: "The world is on the brink. Victoria Neuman is closer than ever to the Oval Office and under the muscly thumb of Homelander, who is consolidating his power. Butcher, with only months to live, has lost Becca’s son as well as his job as The Boys’ leader. The rest of the team are fed up with his lies. With the stakes higher than ever, they have to find a way to work together and save the world before it’s too late."

There's no doubt that the story of Hughie's parents will be a big part of the new season with the addition of DeWitt as Hughie's mom. Hughie believed that his mother was dead but at the end of season 2 it was revealed that she was actually alive and well, and that she'd walked away from her family.

Another story building in season 4 is Ryan's story. Ryan decided to stay with Homelander at the end of the season, smirking at the camera in the final moments of the episode. Showrunner Eric Kripke told EW that the new season is a "battle for Ryan's soul."

Nothing is set in stone just yet. "I don't think the game's over yet. I think [Ryan] saw this one thing and I think we should all be afraid because if he becomes another Homelander, that's obviously really bad for the planet. But he's still Becca's kid and there's still a shot that Butcher can pull him into the light."

Kripke went on to say that both Homelander and Butcher will be in a "tug of war over Ryan" as they fight to get him on their side. "So I think, if anything, we're just hinting at the danger of what would happen if Butcher loses that fight."
