The kids are secretly organizing a surprise birthday bash for their dad. Chief Burns mentions he's off to the docks, but instead, he sneaks away to a bakery to buy a cake, believing his family has forgotten his special day. Chase uncovers this deception and is left bewildered. While the kids and the other Rescue Bots prepare for the party at home, they soon realize that both Chase and Chief Burns are unaccounted for and start searching the town. Eventually, they find the duo trapped in an underground mine, and they rush in to rescue them from rising water and collapsing rocks.
