Tonight’s Castle season 7, episode 16, “The Wrong Stuff,” takes our newly reunited team to outer space! Check out the promo images and read the synopsis ahead of the episode here!

Last week we saw the tense and pretty brutal conclusion to Kate’s abduction by Jerry Tyson, aka 3XK, and his equally psychotic girlfriend, Kelly Neiman. After going about things in a violent manner, Castle turned Tyson’s plan around on him and was able to put his nemesis away for good. In the ground where he belongs. All is right in their world!

Read the official synopsis for Castle season 7, episode 16, “The Wrong Stuff,” below to see what happens next:

“When an astronaut training for a trip to Mars is mysteriously killed inside a Mars simulation, Castle and Beckett don spacesuits to investigate. But when they discover no one inside the sealed simulation could have committed the murder and no one from the outside could get in, the case takes a shocking turn.”

The guest cast includes Yves Bright as Tom Richwood, Gwendoline Yeo as Elise Kim, David Rogers as Viggo Jansen, Sterling K. Brown as Ed Redley, and Maxwell Caulfield as Sir Ian Rasher.

After the last two episodes demonstrated just how resourceful Castle is to the team, we take a look at what’s next for Rick and Kate here.
