Now, a new promo from the 2017 premiere episode of "The Flash" titled "Borrowing Problems From the Future" reveals how Barry and his teammates will deal with the problem. Yes, the plan gives Cisco a reason to use the phrase "back to the future," a phrase he has no doubt been aching to use since he discovered Barry could time travel.

The CW has also released an official synopsis for the episode, which reveals more of the installment's plot. As we saw in previously released photos from the episode, "Borrowing Problems From the Future" will also feature guest star Stephne Huszar as Plunder.

BARRY FIGHTS FOR IRIS — Barry (Grant Gustin) is tormented by his vision of the future where Iris (Candice Patton) is murdered by Savitar. When a criminal named Plunder (guest star Stephen Huszar) shows up in Central City, Barry recalls the villain’s presence in his vision of the future and fears that if he catches Plunder, it will cement Iris’ fate. Confused about Barry’s hesitation to stop Plunder, Wally (Keiynan Lonsdale) decides to step in as Kid Flash. Caitlin (Danielle Panabaker) offers Julian (Tom Felton) a job. Millicent Shelton directed the episode written by Grainne Godfree & David Kob.

"The Flash" returns on January 24. Starring Grant Gustin as the Scarlet Speedster, "The Flash" airs Tuesdays at 8 pm ET/PT on The CW. The series also stars Jesse L. Martin, Tom Cavanagh, Carlos Valdes, Candice Patton, Danielle Panabaker, Keiynan Lonsdale and more.
