In the next episode of "Scorpion," Walter O'Brien (Elyes Gabel) and his girlfriend Paige Dineen (Katharine McPhee) get trapped under rocks when they search for a crash-landed plane.

The trailer and sneak peeks into the upcoming installment titled "Climb Every Mountain" were just released recently and showed O'Brien and Dineen beside a mountain cliff when, all of a sudden, rocks start to fall from the side of it. "Rockslide!" O'Brien shouts as he tries to protect his girlfriend. They both manage to take cover under an overhanging boulder but the rocks are piling around them and blocking their way out of the place. They were supposed to locate a plane that crash-landed nearby and save its occupants but now are sidetracked by their current predicament. Happy Quinn (Jadyn Wong) and Toby Curtis (Eddie Kaye Thomas) contact the trapped victims through a walkie-talkie and ask what is going on with them.

"We're buried in a cave. We can't get out," O'Brien says to the team as rocks and pebbles continue to block their exit. Dineen is clearly looking worried as her partner tries to think of a way out of the newly-formed cave. In the meantime, Agent Cabe Gallo (Robert Patrick) prepares for his upcoming trial but it seems he has a lot to cover. He was arrested for freeing a prisoner from his electronic shackles. If he had not, the criminal would have been killed.

In the last episode, O'Brien, Dineen, and Florence (Tina Majorino) got stuck on an island made out of plastic garbage when their medium-sized boat could not approach them because of the overcrowded jellyfish. They were able to scare off the creatures and save everyone on the garbage island and bring them to safety.

"Scorpion" season 4 episode 10 will air on Monday, Nov. 27 at 11 p.m. EST on CBS.
