In the next episode of "Scorpion," the team led by Walter O'Brien (Elyes Gabel) races against the clock to stop an unmanned ship carrying explosive gases from hitting the shore.

The trailer for the upcoming installment titled "Queen Scary" was just released recently and showed O'Brien, Paige Dineen (Katharine McPhee), Agent Cabe Gallo (Robert Patrick) and the rest of the team getting briefed about an unmanned shipping vessel. Apparently, 20 million gallons of explosive natural gas is on board and is making its way to the shore. "It's going to spill and explode," Happy Quinn (Jadyn Wong) tells Gallo. The ship is on a collision course and the team has to find a way to stop it.

"Our only solution is to stop the tanker," O'Brien tells his team as he drives furiously. Someone seemingly is going to board the vessel as a motorboat is shown racing beside it. "The ghost ship is 30 minutes from barbecuing Long Beach," Toby Curtis (Eddie Kaye Thomas) warns his team on the radio. A collision with the beachside town could potentially endanger many people. It remains to be seen how Team Scorpion will stop the rampaging tanker from blowing up the seaside town.

In the last episode, O'Brien and the team stopped an organized group of thieves from stealing one million dollars from the Elia bank account. They created a fake bank account with the money which the thieves thought was real. They then tried to escape on their motorcycles but Gallo was on their tail. He appeared out of nowhere and intercepted their path.

The bikes made a sudden turn which knocked them off their seats as they fell to the ground. Gallo captured them and brought them to justice.

"Scorpion" season 4 episode 6 will air on Monday, Oct. 30 at 10 p.m. EDT on CBS.
