Noah Wyle stars as the leader of a group fighting aliens in the second season of "Falling Skies" on TNT.

The producers of TNT’s "Falling Skies" had a clear vision of what they wanted for the second season of the breakout show.

They wanted the sophomore season of the science-fiction drama, premiering Sunday, June 17, at 9 p.m., to be bigger, better and badder — and if the first few new episodes are any indication, viewers can expect Tom Mason (Noah Wyle), Captain Weaver (Will Patton) and the boys of the second mass militia to push back after being scattered by skitters.

“The objective this season was to ramp everything up: the stakes, the personal drama, the tension,” said executive producer Remi Aubuchon. “If the first season was about our characters trying to cope with the trauma of having their world turned upside down, this season is about taking action and fighting back.”

After willingly entering the alien ship at the end of season one, Mason hopes that he can found out more about what happened to his son. He soon discovers that the aliens are willing to help, but that they want human resistance groups to surrender and relocate to a “safe zone.”

After being released, Mason reunites with a unit that has been aggressively ambushing skitters while looking for refuge for the upcoming winter months.

The new season of "Falling Skies" brings the audience closer to the invading horde as the individual alien characters are developed. There are also more surprises to come as viewers find out how connected Mason’s son Ben really is to the aliens.

The action lacking in first season is now intensified and highlighted in a scene in which Mason jumps into the back of a burning truck to fire a machine gun at an oncoming group of skitter troops and saving a group of soldiers in the process.

Also, the CGI effects are improved. The aliens look more realistic and the detail of the overlords and skitters looks less like it came from a computer and more natural on the screen.
