The Boys and The Winchesters alum Jensen Ackles has his next acting project already lined up.

Prime Video’s Countdown, a new 13 episode series from Derek Haas (The Chicago franchise on NBC, and FBI: International on CBS), will star Ackles, who is currently under a first-look television deal with Amazon MGM Studios.

The project marks the first series from Haas under his new exclusive overall deal with Amazon MGM Studios. Haas both created the new series and serves as executive producer and showrunner.

Countdown picks up the pieces after a suspicious murder in broad daylight, which leads to LAPD officer Mark Meachum (Ackles) being recruited to join a secret task force of undercover agents from all branches of law enforcement to investigate.

But as the truth of a more sinister plot comes into focus, the team must overcome their conflicting personal agendas to unite and save a city of millions.

“I had an incredible experience working with the Prime Video team on The Boys and am delighted to be able to continue that relationship on Countdown,” said Ackles. “I simply cannot wait to partner with Derek and the rest of our Countdown family to bring this story to life.”

“We are incredibly excited to be back in business with Derek Haas,” said Vernon Sanders, head of television, Amazon MGM Studios. “He has an undeniable ability to enthral audiences with thrilling storytelling and heart. We cannot wait for Prime Video’s global customers to experience this dynamic series, led by our very talented star, Jensen Ackles.”

Speaking in a statement Derek Haas said “I am thrilled to be working again with Jen Salke and Vernon Sanders and all the excellent people they’ve assembled at Prime Video. I love making shows that keep you on the edge of your seat with nonstop action, drama, surprises, and suspense, and I can’t wait to work with Jensen and for everyone to see Countdown.”

Countdown is produced by Amazon MGM Studios, and will stream exclusively on Prime Video in more than 240 countries and territories worldwide.
