The SS Tipton is going straight in the path of endangered blue whales motivating Zack, Cody, Bailey, and Marcus to try their best to change the ship's course. They lock themselves into the engine room hoping the whales will safely pass, however they discover it's not as easy as it seems. Cody begins to faint due to heat exhaustion, Marcus becomes desperate for water, and Zack loses it and tries to break free. Eventually, Kirby and Mr. Moseby break into the engine room to attempt to stop them, but after seeing the whales on Cody's laptop, they decide to go along with plan.
