"Snowpiercer has been an incredibly successful series for us that
continues to capture the imagination of viewers, grow audience,
and maintain strong ratings," said Sam Linsky and Adrienne O'Riain,
co-heads of scripted original programming for TBS, TNT, and truTV.
"All of our seasons embark on an emotional, unexpected ride, and
the well-plotted storylines will continue to evolve and remain
relevant to audiences. We're excited to keep the train running into
season four."

At the end of Snowpiercer Season 2, Layton (Daveed Diggs) and Ruth
(Alison Wright), who were banished to Big Alice's compost car,
plotted to take back Snowpiercer. With the help of Javier (Roberto
Urbina) and Alexandra (Rowan Blanchard), Layton and Ruth made it
back to Snowpiercer and rallied with their supporters. Josie (Katie
McGuiness) destroyed the Aquarium car separating Snowpiercer's head
from the remaining 1,023 cars. With Layton in command of a 10-car
"pirate train," he and his team rushed to Breslauer Research Station
to find Melanie (Jennifer Connelly).

Season 3 picks up with Layton (Diggs) and his inner circle
commanding a small pirate train in search of Melanie (Connelly) and
a possible warm location to restart civilization, aided by a
newfound survivor. Back on Snowpiercer, Mr. Wilford (Sean Bean) is
consolidating power, foiled only by secret allies of Layton's hidden
on the train, committed to the cause.

Emmy nominee Archie Panjabi and Chelsea Harris join the Season 3
cast, with Mike O'Malley being elevated to a series regular.
Snowpiercer season three also stars Oscar winner Jennifer Connelly,
Grammy and Tony Award-winner Daveed Diggs, Sean Bean, Rowan
Blanchard, Emmy nominee Alison Wright, Mickey Sumner, Iddo Goldberg,
Katie McGuinness, Tony Award winner and Grammy nominee Lena Hall,
Annalise Basso, Sam Otto, Roberto Urbina, Sheila Vand, and Steven
Ogg.

Snowpiercer  is executive produced by Graeme Manson, Aubrey Nealon,
Marty Adelstein, and Becky Clements, Matthew O'Connor, Ben Rosenblatt
and Scott Derrickson, and the original film's producers, including
Bong Joon Ho, Miky Lee, Jinnie Choi, Park Chan-wook, Lee Tae-hun, and 
Dooho Choi. The show is produced by Tomorrow Studios, along with CJ
Entertainment. ITV Studios handles international distribution.

Seasons 1 and 2 are currently available to binge on the TNT app, with
Season 3 set to premiere on TNT early next year.
