A new mission requires team Scorpion to explore a bat cave in the upcoming episode 6, titled "Bat Poop Crazy," of the third season of the American action drama "Scorpion."

Instead of being busy preparing for the Halloween, team Scorpion has a huge task to complete. They have to infiltrate a deep, vast cave system, in order to put a stop at the growing number of bats from destroying the North American ecosystem. Apart from that, the team has to stage a number of photos depicting having fun at Halloween parties so Walter (Elyes Gabel) can use it as reference to his past for his upcoming immigration inspection.

The promo trailer for the upcoming "Scorpion" season 3 episode, "Bat Poop Crazy," shows the team braving the depths of the cave. However, it seems scarier than what they have imagined since one wrong step could mean the end of their lives. Things will even get scarier once they arrive at the area where all the bats flock.

In one of the sneak previews, Toby (Eddie Kaye Thomas) and Paige (Katharine McPhee) direct Walter's staged photoshoot that would best represent his Halloween experience over the past years. He enlists the help of Happy (Jadyn Wong) to be his partner in the photoshoot.

However, the team realizes that what they are doing is more taxing than they have thought. Paige and Toby had to tell the pair how to act like normal people in Halloween, while Happy and Walter's expressions look forced.

Meanwhile, the previous episode, titled "Plight at the Museum," saw the team Scorpion doing what they thought was a simple job at the Los Angeles Natural History Museum. They did not expect that the mission would turn out deadly when thieves attempted to steal a very valuable item from a rare gem exhibit so it can be used to make a nuclear bomb.

"Scorpion" season 3 airs Mondays at 10 p.m. on CBS.
