On the Next Episode of ABC's THE BACHELOR...

A two-night Bachelor special event begins with Sean whisking the remaining 11 bachelorettes away to picturesque Whitefish, Montana, to explore his romantic connections. But the outspoken Tierra and sweet natured Jackie Face Off in the dramatic two-on-one date, and one of them will be sent home immediately. The Bachelor attempts to escalate his relationship with Lindsay to new heights when the couple takes an astounding helicopter ride over the gorgeous mountains of Montana's Glacier National Park. Eight women get to compete in a Montana relay race, including milking goats, with the winning team getting to spend more time with Sean. And one controversial bachelorette continues to cause a firestorm in the house, leaving Sean to worry if he will ever find his wife here, on "The Bachelor," TONIGHT, FEBRUARY 4 (8:00-10:01 p.m., ET), on the ABC Television Network. The second part of "The Bachelor" special event, Episode "1706," will air on a special night and time, TUESDAY, FEBRUARY 5 (9:00-11:00 p.m., ET).

Sean and Lindsay take in the spectacular scenery at Glacier National Park, and Lindsay's heart soars during a romantic dinner. Is this the same playful woman who arrived in a wedding dress a few weeks ago? She finally opens up to Sean about the difficulties growing up as an Army brat. As the romance heats up, Sean surprises her with a special concert by Country star Sarah Darling on the streets of downtown Whitefish -- but will Lindsay get a rose?

Eight of the bachelorettes discover canoes, hay, a wood chopping station and goats at a local lake - uh-oh! They are once again split into two teams for a Montana relay race. The final part of The Challenge will be milking a goat and chugging its milk! The winning team will be rewarded with extra time with Sean that night, while the losing team will head back to the hotel. One team finally squeaks by to win. But Sean makes a surprising decision when it comes to the losing team that is bound to upset the winners. And to make things more interesting, Tierra, upset that she will be on the two-on-one date, shows up at the after party. Will her secret rendezvous hurt or help her get the rose the next night?

It's a blistering competition between Tierra and Jackie during the two-on-one date. Sean takes both women on a horseback ride through the Montana outback, only to have the normally charming Jackie take The Bachelor aside and stab Tierra in the back. Will he listen to her? Tierra, in an attempt to save herself, reveals a shocking detail about her personal life. Meanwhile, Sean is left to sort out his feelings and make a very difficult choice which leaves one bachelorette in tears.

The final cocktail party is a boiling cauldron of outrage. It's one woman against the rest of the bachelorettes. Frustrated by all the drama, Sean tries to get to the bottom of the situation, but just feels more confused than ever. He confides in CHRIS HARRISON that he's beginning to doubt he will ever find his soul mate among these women. At the rose ceremony, everyone is stunned by whom Sean chooses to send home. Nine women will join him as they set off for their next destination, the Colorado Rockies.
