In the most dramatic season finale ever, the only thing our couples know is that this is their last day in Paradise… unless, as host Chris Harrison explains, they decide, after some tough conversations, that the potential for love in their relationship is real enough that they want one more date in Paradise. That date would end with a fantasy suite card and the opportunity to spend the night alone together behind closed doors. Their other choices are either to leave together and explore their relationship outside of Paradise, or to just go their separate ways.

A new arrival doubles her odds by liking both boys and girls. Hopeful latecomers have their sights set on other women's men. A woman offers a man his first date in Paradise, and he accepts, even though he has been getting cozy with a virgin in Paradise. Meanwhile, a more assertive lady takes a shot at a man who just dumped one girl to focus on another. Later, two women storm out of Paradise.

One unhappy guy's love triangle hits a setback, but his hurting honey surprisingly declines a date with a new arrival. The new arrival has trouble finding another date but one woman accepts his offer in order to escape the drama in paradise. A newer, hotter arrival has an easier time getting a date when the first woman he asks says yes, even though her last date thought they were a thing. The double-date takes a turn when someone gets seasick. Meanwhile, on a more romantic date, an eager suitor takes a single mom to a Mexican town fair. Later, a single fellow decides to leave and one mixed up man finally ends things with a bachelorette who seeks solace in everyone's favorite bartender.

At the rose ceremony, Jasmine's already departed Don Juan makes a shocking return to hand her one last rose before leaving again for good. Two American beauties are not as fortunate, as they are sent packing. A late arrival's date involves a Mexican form of wrestling, and a "tickle monster" moves into Paradise with a date card. Plus, as one love triangle is forming, another is about to explode. Later, members of the cast join host Chris Harrison in a special studio session and Corinne returns to tell her side of the story.

Tonight's wildly entertaining episode of Bachelor in Paradise, begins, ironically, with the arrival of a virgin with a date card. Although her "friend" from Nick's season of The Bachelor warns the virgin that her man would be a "waste of time" asking, he lets her know that, despite what she might have heard, he would love to go on a date with her. And so he does. At the rose ceremony, one man, who is interested in two women, has to choose one to give his rose to, knowing that the other one will probably be going home, while another man finds himself torn between the "right option" and the "more exciting option."

Two new arrivals bring sex, jealousy and deceit to Paradise. Meanwhile, a frustrated husband-hunter has her own troubles when she receives a date card and doesn't have anyone to ask out. The worst fear of one comes true when a meddlesome matchmaker names the new potential couple. A lovely but left-alone lady departs Paradise and says goodbye to bartender Wells, who she secretly has a crush on. Paradise then heads to the studio where host Chris Harrison interviews DeMario Jackson and Corinne Olympios.

The fun begins when a cast-off cast member from Rachel's season of The Bachelorette washes up with a date card burning a hole in his pocket. Later, one frustrated female, who doesn't know where she stands with her man, makes it clear she would love to go on a date with the newcomer. During the cocktail party leading up to the first rose ceremony, one guy tells one of the women he wants to slow things down. The morning after, one lucky loser receives a rose from a buddy rather than from his prospective bride, and one woman's pretty boy shows up with a birthday cake for someone else!

Carly and Evan exchange marriage vows in Paradise before an assemblage of their family and friends, including many of our Bachelor favorites. Then, it's time for the tears to flow, including from the bride and the groom… and Ashley I. too! Later, the cast returns and sits down with host Chris Harrison for a thought-provoking conversation. Once the show resumes, the cast tries to pick up where they left off. Watch one couple's relationship heat up, while the production timeout changed the momentum for others. Meanwhile, one desperate and lonely lady wants a date card to help her get something new started, but is disappointed when it goes to someone she thinks doesn't need it. Will this date mark the beginning of what could be our next Carly and Evan?

Looking for a second chance at love on the fourth season premiere of the highly anticipated Bachelor in Paradise, the cast arrives one by one to their own private paradise in the gorgeous town of Sayulita, located in Vallarta-Nayarit, Mexico. The cast, comprised of former fan favorites and controversial characters from The Bachelor franchise, live together along the shores of Paradise beach, share exotic dates, and explore new romances, all for another chance to find love. They all left The Bachelor or The Bachelorette with broken hearts, but now they'll travel to a romantic paradise, hoping to turn a potential summer fling into the real thing.
