Fan-favorite JoJo Fletcher, 25, gets a second chance at happily ever after, as the season begins with her meeting 26 handsome bachelors. Will one of them be her Prince Charming? Before the evening begins, former Bachelorettes Kaitlyn Bristowe, Desiree Hartsock Siegfried and Ali Fedotowsky offer their support and advice. And it wouldn't be a first rose ceremony without a surprise! Before the ceremony can even begin, an unexpected visitor from the past arrives and pulls the shocked Bachelorette aside, as the other men wonder if this man is new competition for JoJo's heart. At the end of the night, 20 men continue on in the hopes of winning JoJo's heart.

Twenty anxious men hope to get their love story with JoJo off to a good start. The first group date gives 10 lucky bachelors a chance to see sparks fly when they head to a firefighting training facility, where one of the guys might need saving himself. JoJo and Derek get to pick their own adventure, and they choose a romantic picnic by the Golden Gate Bridge in San Francisco. Six bachelors get a dream date to ESPN's popular show SportsNation, with hosts Max Kellerman and Marcellus Wiley. The hosts are sure they will be able to help JoJo find a perfect match, but Chad seems determined to shock and awe all the way up to the rose ceremony.

The men are still in shock after Chad stays as part of the group of 17 remaining men - despite his aggressive behavior - and begin to feel the pressure as the competition heats up. Chase and JoJo go to a hot yoga class during the day, which ends with a surprise performance by country star CHARLES KELLY. Plus, a group of unsuspecting bachelors is about to come clean about their sexual experiences - in public! Meanwhile, Chad has reverted back to his hot-head ways, almost leading to fisticuffs. James Taylor is treated to a good old-fashioned date with swing dancing, topped off by a trip to Lover's lane. An impromptu pool party replaces the cocktail party, and the drama begins as one man calls out Chad for his bullying behavior, and Chris Harrison takes matters into his own hands. Will this be the end of the road for Chad?

SPOILER: The guys go to Urguguy and find a magazine of what says that JoJo is still in love with her ex Chad and she finds out and talks to the guys and after that Alex finds a new enemy and starts blaiming everything on Derek for reassurance. JoJo decides to cancel the cocktail party and goes strait to the Rose Ceremony. She sends 3 guys home.

JoJo and the eight remaining men move on to the beauty and history of Argentina's exciting capitol, Buenos Aires. The Bachelorette hopes to get things back on track this week and make progress with some relationships, but for the first time in franchise history, there will be a second two-on-one date. Wells takes a romantic walk through the city with JoJo and they have the opportunity to participate in a performance art piece, Fuerza Bruta, which will hopefully ignite their passion. JoJo escorts five men for a day of fun in the La Boca neighborhood of the capitol, but it ends with tempers flaring as the competition intensifies. Chase and Derek, two of JoJo's favorite bachelors, are the unlucky guys going on the two-on-one date. The guys aren't the only ones who are anxious. JoJo stuns the remaining men by suddenly leaving the rose ceremony.

The drama of Buenos Aires is behind JoJo, but she still must determine which four men will have the chance to take her home to meet their families. So it is on to the countryside, steeped in Argentinian gaucho culture. There is a crucial date for Alex, who charms JoJo on a romantic day of picnicking and horseback riding. A private jet whisks Jordan and JoJo away for a tryst at an Argentinian vineyard to make wine, but later, he shares a stunning revelation which changes how JoJo feels about him. Bad weather cancels plans for a group date, but Robby, Chase and James Taylor still have a blast as the only date rose this week is up for grabs. Finally, Luke and JoJo share time horseback riding and skeet shooting, and his gentle way only makes her choice more difficult. JoJo faces a difficult emotional decision at a critical rose ceremony, as she looks to join the final four men in their hometowns.

JoJo's world tour returns to the United States and travels across the country to visit Chase, Jordan, Luke and Robby. Her resilience is about to be tested by the men and their loved ones, as she tries to figure out from the people who know them best if these bachelors are ready to be married.

The end of the hometown dates rose ceremony, followed by overnight dates with the 3 remaining men in Thailand.

It's an exciting, unpredictable reunion viewers won't want to miss as JoJo faces some of the most memorable bachelors from this season - including Alex, Chad, Chase, Christian, Daniel, Derek, Evan, Grant, James Taylor, Luke and Wells - who have returned to tell their side of the story.
