First comes marriage, then comes getting to know each other. At least that’s how it goes on “Married at First Sight.” The FYI reality show returns for Season 3 in December, and a new trailer shows all of the participants just before heading down the aisle.

“Married at First Sight” does exactly what the title indicates. The people in the below video are getting ready to meet their spouses for the very first time. They have trusted four experts to match them with their scientific soul mate. The participants meet their supposedly perfect match at the altar.

In the trailer, three brides and three grooms nervously get ready to meet their new spouse. One bride, however, seems to be having second thoughts. “Okay, I’m changing my mind,” she says. “Let’s go back.”

However, the trailer’s title card reads, “There’s no turning back,” so it seems like she’ll go through with the marriage.

Watch the “Married at First Sight” Season 3 trailer below:

As previously reported, “Married at First Sight” Season 3 will take place in Atlanta, but the series will bring back the four experts that have been with the show from the beginning. Sociologist Dr. Pepper Schwartz, sexologist Dr. Logan Levkoff, psychologist Dr. Joseph Cilona and spiritual advisor Greg Epstein will match the couples.

The new cast will have to hope that they have better results than last season’s participants. None of the cast members from “Married at First Sight” Season 2 stayed together. Luckily, two of the Season 1 couples had better luck. Jamie Otis and Doug Hehner as well as Cortney Hendrix and Jason Carrion have remained married and continue to chronicle their relationship struggles on “Married at First Sight: The First Year.”

“Married at First Sight” Season 3 premieres on Tuesday, Dec. 1, at 9 p.m. EST on FYI.
