In the highly anticipated series premiere, hosted by CHRIS HARRISON and former Bachelor contestant MELISSA RYCROFT, the competition begins as 19 former participants from The Bachelor and The Bachelorette move into the Bachelor mansion to meet their fellow competitors. It isn't long before they face their first challenges: a game of Twister, Bachelor style; a group date in the sun and, later, under the stars; and a dreaded elimination.

Fifteen contestants continue to compete for $250,000 and a second chance at love. This week, lips will lock and there will be overnight dates in Sin City (Las Vegas). Plus, there's a high-speed chase for immunity and another dreaded elimination.
