Mr Pickles

A man and a woman are floating on a yellow inflatable raft in a body of water, the man holding the woman as they both smile. The scene cuts to a black and white dog in the water looking at the man, then to a close-up of the man's face showing shock as he holds the woman's head, before returning to the couple on the raft. This sequence repeats. The setting is a lake or river with a shoreline of green trees and bushes.
