Season 12 begins with JoJo Fletcher getting advice from former Bachelorettes Kaitlyn Bristowe, Desiree Hartsock Siegfried and Ali Fedotowsky before welcoming 26 bachelors to the mansion. One gentleman tries to charm JoJo with a song he wrote for her, while a DJ brings R&B group All-4-One to serenade her. One shy guy shows off his Scottish heritage by wearing a kilt; and one man attempts to stand out by riding in on a unicorn.

JoJo takes 10 lucky men to a firefighter training facility where they undergo boot camp-like challenges. Next, one excited suitor gets the first 1-on-1 date of the season and is whisked away to San Francisco for a picnic by the Golden Gate Bridge. The next day, JoJo meets six men on the set of ESPN's "SportsNation" where they are introduced to hosts Max Kellerman and Marcellus Wiley, who try to help JoJo find the perfect guy.

One lucky bachelor enjoys a day of hot yoga with JoJo and a private performance from country star Charles Kelley. Also: one suitor creates chaos when he announces he doesn't want to go on the group date; 12 guys visit an L.A. theater where they are required to share stories about their sex lives in front of a live audience; and JoJo takes one bachelor swing dancing and to Lover's Lane.

JoJo joins the guys for a fun-filled day in the pool but realizes they are distracted by the recent drama involving one bachelor. After the rose ceremony, the 14 men who remain travel to the Laurel Highlands of Pennsylvania where a suitor gets a one-on-one date in the woods. Later, 11 bachelors visit Pittsburgh's Heinz Field and play football with Ben Roethlisberger, Hines Ward and Brett Keisel; and two guys go on a dreaded two-on-one date, but only one gets a rose.

Chad confronts the men after not getting a rose. But soon the 11 remaining guys jet off to Uruguay with JoJo, where one man has to defend himself against unflattering gossip. Also, JoJo becomes the target of ugly tabloid reports that she's on the show for the wrong reasons and must argue her case to the men.

JoJo and the eight remaining bachelors visit Buenos Aires, where a second dreaded two-on-one date occurs. Also: five guys enjoy a day with JoJo in the La Boca neighborhood; and one lucky man goes on a sexy date at a performance art show. At the rose ceremony, JoJo stuns the men when she runs out.

JoJo and the men visit the Argentinian countryside, where the first date gets off to a rocky start. Later, a private jet whisks JoJo and one lucky guy away to a vineyard. During dinner, the bachelor makes a shocking admission. A date with three suitors gets rained out, so JoJo spends the day with them ordering room service, pillow fighting and watching the Brazilian version of "The Bachelor." A one-on-one date allows one man to show off his horse-riding skills.

JoJo goes on hometown dates with the four remaining bachelors. First, she visits a family who has been affected by divorce. Next, she visits a suitor's high school and learns he's not as confident as he seems. Gossip surrounds one guy; and one bachelor takes her to an old-fashioned barbecue. At the rose ceremony, JoJo is blindsided by a surprise confession from one of the men.

The rose ceremony after the hometown dates continues and one man is sent home. Later, JoJo and the three remaining bachelors fly to Thailand for their exotic overnight dates, where JoJo realizes she is in love with two men.

JoJo and 18 of the most memorable men from the season return to discuss their experiences, including the controversial Chad. Also: a sneak peek at "Bachelor in Paradise 3"; a look at lighthearted bloopers; and a peek at the end to JoJo's emotional journey.

JoJo introduces guy1 and guy2 to her family and they immediately connect with one of them but have reservations about the other man. JoJo then struggles to choose between the two bachelors, as her emotion-filled journey comes to an explosive end.

Emotions run high as JoJo talks about her two final bachelors from this season. She will take viewers back to those last days in exotic Phuket, when she needed to make her life-changing decision and both men will join to discuss the outcome.
