Water Damage for MacBook pro

I spilled some water on Mac book pro laptop on the keyboard. I dried it off as best as I could. But when came back to the laptop the screen was black. I put it in a tub of rice, and it died while it was in there. The charging icon came on the screen so I put it on the charger. When I tried to turn it on, it made the sound that it was powering on, but the screen was still black. Now a flashing icon with a folder with the question mark is coming on the screen. What should o do?
