In the next episode of "Scorpion," Walter O'Brien (Elyes Gabel) and the rest of the team try to save endangered animals from poachers.

The trailer for the upcoming episode titled "Grow a Deer, A Female Deer" was just released and showed Sylvester Dodd (Ari Stidham) on a truck getting chased by two men on four-wheelers. Dodd is being pursued because he has a deer on the truck that the poachers want. However, he was able to stop the chasers by throwing explosive containers at them which exploded in their path. The poachers' get knocked down by the blasts and Dodd is able to escape. "Dudes with guns are coming to collect!" he yells.

In another scene, O'Brien, Paige Dineen (Katharine McPhee), Toby Curtis (Eddie Kaye Thomas), and Happy Quinn (Jadyn Wong) run frantically in order to save an animal as poachers pursue them. "The poachers will be the ones on the endangered species list," O'Brien tells the group in the last scene.

It remains to be seen how Team Scorpion will be able to save the endangered species from the stubborn poachers.

In the last episode, O'Brien and his crew went on a mission in Norway to save the surrounding environment from methane poisoning. They did this by cloud-seeding so that the snow would diffuse the methane in the atmosphere. The crew went to a hotel and hijacked a helicopter that helped circulate the particles in the air. These chemical particles were taken from the hotel and blasted into the air with bazookas.

The team eventually was able to stop the build-up of methane thereby saving others once again. However, their ex-colleague Mark Collins (Joshua Leonard) escaped from Cabe Gallo's (Robert Patrick) custody in the process.

"Scorpion" season 4 episode 3 will air on Monday, Oct. 9 at 10 p.m. EDT on CBS.
