Mark Suppelsa has been sober since 2012, but as any alcoholic can attest, the daily struggle for sobriety is real. The WGN-TV anchor's battle with alcoholism is the subject of a song written by his daughter, Ava Suppelsa.

'Finish Line' not only shows how proud Ava is of her father, but recognizes the ongoing struggle her dad faces every day.

One day at a time, he fights for sobriety
Living in a war that he's battling silently
He can almost see the other side
12 steps away from the winning mile
He'll make it just in time
And we're waiting at the finish line...
