It's an exciting, unpredictable reunion viewers won't want to miss, as the most memorable bachelors from this season - including James, Ben, Michael G., Mikey T., Zak W., Juan Pablo and Jonathan - return to confront each other and Desiree one last time on national television to dish the dirt and tell their side of the story. The last eliminated bachelor, Zak, seeks closure about what went wrong with his relationship with Desiree. Sparks will fly as the villainous James and Ben try to explain their actions. Plus, the "Bachelor Bus" makes some surprise stops to crash fan viewing parties in Los Angeles and New York, and three favorite Bachelorettes advise Desiree on dealing with the men who were there for the "wrong reasons."

After enduring heartbreak when Sean Lowe sent her home last season on "The Bachelor," Desiree Hartsock refused to give up her fairytale dream of romance, and she returned for a second chance at love. After surviving shocking twists and turns, Desiree narrowed down the 25 bachelors to three fabulous guys - Brooks, Chris and Drew. While she was ready to give her heart completely to Brooks, he did not share her feelings. Desiree was expecting fireworks when she met Brooks in Antigua, but when he broke up with her very unexpectedly, she was left crying at the edge of a dock, devastated, heartbroken, hopeless and ready to go home. In this week's emotional conclusion, Desiree must decide if she can move forward with the other two men or if her hope of finding love has been ruined.
