Married at First Sight - Season 13 (2021)

For the first time, our five couples are waking up married to a stranger. But before they can leave on their honeymoon, each spouse will have brunch with their new in-laws. While some are readily accepted into the family, others learn information they'd rather not know, including a warning that one bride is likely to "explode."

Five pairs of newly-wed strangers are whisked away to the Florida Keys and begin the journey of learning who they've just married. While one groom learns that his bride is very hard to please, another couple's honeymoon is over before it even begins.

The honeymoon continues in the Florida Keys for just four of our couples. Despite trying exciting new activities and taking stabs at romance, some start to learn that their differences are greater than they imagined.

The couples return to Houston to live together for the first time as husband and wife, but settling into day-to-day life is a rough transition for anyone. Now our stranger spouses are challenged with the struggles of everyday life and the decision to fight for their marriages--or flee from them.

As the newly-married couples dive into domestic life and welcome friends to housewarming parties, one husband sees red flags, while another wonders if he was ready for marriage at all.

As our five pairs of married strangers enter their third week of marriage, one couple contemplates using the "L word" while the other four do anything they can to ignite a fire between them.

Dr. Viviana gives our five couples some sexy assignments to help build trust and intimacy. While some couples enjoy the added spice, others feel distance from their partner. And after calling her husband by the wrong name, one wife finds herself locked out--literally.

Having reached their one month milestone, love is growing for some, but one husband is fed up with his wife's lies. Meanwhile, an unforeseen death alters the course of another couple's journey.

As the couples settle into everyday life, some look forward to their future together, while others begin to question everything. And when one bride calls for an expert intervention, things get intense quickly.

With Decision Day looming, the spouses meet with the experts to discuss unanswered questions about their marriages. One wife shows up less than sober, one husband ends up in tears, and another reveals that he's never been attracted to his wife at all.

With only two weeks until Decision Day, the couples travel to a ranch in the country for a break from their everyday lives. Will the time away be the dreamy escape they're hoping for, or a trip down a rocky road?

With less than two weeks until Decision Day, the spouses revisit their pasts in order to discover more about one another. However, when a secret is revealed within one couple it threatens to break their marriage and future.

With Decision Day fast approaching, each spouse spends time with friends and loved ones as they weigh the life-changing decision of whether to stay married or get a divorce.

After eight weeks of working on their marriages, it's Decision Day for our five couples, who must now decide once and for all whether they want to stay married or get a divorce. For some, it's not as easy as they thought it would be.

The Houston cast reunites with host Kevin Frazier to discuss their eventful season and what has happened since Decision Day. Nothing is off limits and emotions run high as the couples share shocking updates on their relationships and revisit painful moments from their marriages.

The reunion continues as tensions mount between Zack and Michaela. The experts reflect on the season and work with two of the couples to mend their broken relationships. Mounting frustrations within the group lead to two dramatic departures.
