Tell the whole story

Every chess position tells a story. At least thats what I like to tell my students when I am teaching them. And when I give them a position and tell them who is to move and win, then they have to tell me the complete story to the end before I allow them to move any pieces.

Take for example the following position:

It is White to move and win!

My students must now study the board and give me the correct sequence of moves, or as I like to say, "Tell me the story of how White wins."

In this case the tactical theme is Back Rank Combinations.

See if you can tell me the whole story of how Whie is to win this game. Watch out, as this is a tricky story.

(Please post your answers but please do not comment on anybody elses answers as I am looking to see who can come up with the Whole story. Thanks)
