Fourteen up-and-coming surfers arrive at the World Surf League's state-of-the-art Surf Ranch in Lemoore, Calif.

Two men and two women meet in the final showdown; surfing champion Kelly Slater surprises the finalists with a coaching session; one man and one woman are crowned the winners and receive the $100,000 grand prize.

The eight remaining surfers give surfing lessons to Bachelor Nation fan favorites Hannah Ann Sluss and Mike Johnson; the surfers light up the night with a beach party and nighttime surf session under the moonlight.

The remaining eight surfers hop on their boards for a tug-of-war, surfer style, to earn extra time on the wave and earn a prize; teams choreograph synchronized runs for a crossovers wave challenge.

Alliances and friendships are put to the test as the 12 remaining contestants vie for the title of Ultimate Surfer; the surfers compete in a breath-hold buoy bace and show off their backside in the wave challenge.

The surfers use their strength, balance and stamina to stay on a barrel roll; teams discuss new strategies to take out the front-runners and focus on winning; surfers are sent home.
