It's down to the final four and the stakes are higher than ever. Each team of two is tasked with creating in-home demonstrations showcasing products from the Honest Company as the company's founder, Jessica Alba, serves as advisor to Arnold Schwarzenegger along with Patrick Knapp Schwarzenegger. Personalities clash as each team tries to agree on the best creative plan for their presentation to win the task. Later, in a tense boardroom, Arnold terminates a player from the losing team but doesn't stop there. Next, the finalists are presented with a task from Carnival Corporation. They are expected to create an ad campaign, host a party and produce a variety show that can't be accomplished without some familiar faces. Curtis Stone also makes a special appearance to help the teams in their attempt to showcase the food on the cruise. Tempers flare as the clock is ticking on their biggest challenge yet.
