Executive producer Marc Guggenheim said that the exciting bit in the episode would be to see Ray Palmer (Brandon Routh) to finally take on his role as A.T.O.M and fights his first battle, and fans will get to see the spectacular suit, "in its full glory."

"This show is not Flash - we don't traffic in these sort of visuals - so it's a big deal for us to get this kind of character on the show, looking the way he does," he added.

From the synopsis and the preview of the episode, we know that one of the main storylines will have to do with Ra's al Ghul (Matt Nable) capturing Malcolm Merlyn (John Barrowman) and keep him at Nanda Parbat. But Oliver will come to his rescue.

Here's the official synopsis for the episode:

"Malcolm is captured by Ra's al Ghul (guest star Matt Nable) and taken to Nanda Parbat. Because of his love for Thea, Oliver considers saving Merlyn. Ray is obsessed with finishing his Atom suit so he can save the city but Felicity fears he is heading down the same path as Oliver and tries to pull him out of the lab."

Nanda Parbat will air on February 25 at 8 p.m. ET.
