Five teams remain and this week the teams are surprised to learn they are taking a trip to San Diego's Mission Beach. For their challenges, the beauties study radio waves and electronics, while the geeks create their own unique fitness routine. Before the challenges begin, the teams share some bonding time on a yacht, but tempers flair when one beauty lashes out at a geek for sending her team to the elimination room. Two teams go to the elimination room, but only one team goes home.
