Kochira Katsushikaku Kameari Kouenmae Hashutsujo

Synopsis

One day, when Ryo is eating some shaved ice at a sweets shop, the old lady who runs the shop mentions that she's getting rid of her old hand-cranked shaved ice maker in favor of an electric one. Ryo offers to take it off her hands, and she gives it to him as a present.
Ryo brags about the machine, and plans to make the best shaved ice with it, but Reiko mocks him, and tells him if that's the case he should be using higher quality ice. He convinces Nakagawa to order some ice from the arctic, and they deliver a mountain of ice. After using it to make shaved ice, there's still too much left, and Chief Ohara tells him to get rid of it.
Ryo then comes up with a plan; by making a ski slope out of shaved ice, he can get rid of the ice mountain, and also make a bunch of money at the same time. However, as a police officer he's not allowed to start a business. Will he get away with this or will the chief catch him red-handed?
