Explosively controversial former bachelorette and fiancée of Jake Pavelka, Vienna Girardi struggles during her second chance at love as she is forced to be housemates with not only her former husband-to-be, but also his new belle Gia Allemand.

Kasey and Vienna continue to attack Jake as the "Target on My Back" challenge is unveiled, allowing each woman to answer a question by throwing paint-soaked balls at targets on the backs of the men, then the sides switch.

The contestants showcase their bodies in a synchronized swimming event; Vienna and Kasey lose control of the Pad to Jake and his mounting number of allies; Melissa becomes furious with Blake while ex-fiancés Michael and Holly share a defining moment.

A new man in the house has emerged as the most unpopular guy in the pad; in the "Kissing Challenge" each man will kiss the women and then the roles will switch, after which everyone will vote on who has the "best lips" in the pad.

The competitors are tasked with pairing up as couples in order to compete as teams for the duration of the competition as they begin their journey with the challenge, "The Nearly-wed Game," which tests how well they know one another.

The remaining four couples are tasked with mastering a Cirque du Soleil routine in 24 hours as their acrobatic performances will be judged, yielding one couple being sent home; the winning couple chooses an opposing team to face in the finale.

After beginning the journey with 18 unforgettable characters from previous seasons of "The Bachelor" and "The Bachelorette," the end of the road has come for the remaining contestants who must now pull out all the stops as they attempt to find love.
