"Answer back, brother"

For the past two years, Spencer Isaac has been writing letters to his big brother Chris.  He never hears back.  He doesn't really expect he ever will.

Spencer and Chris grew up 4 hours north of Sackville, New Brunswick, on the Listuguj Mi'gmaq First Nation in Quebec. They were both students at Mount Allison University.

On a cold November night in 2012, Chris Metallic left a party in the small university town of Sackville New Brunswick - and vanished.  Chris was 20 years old and in his third year of university. Spencer was 18 - and just getting used to life away from home. 

There are still missing person signs up on telephone poles in Sackville. The smiling face, a plea for information, the promise of a 5,000 dollar reward.  In local coffee shops and living rooms, Chris Metallic's disappearance has been discussed a million times over,

For Spencer and his mother, Mandy Metallic, it has been two years of hell, trying to grieve and hope at the same time. Through it all, Mandy keeps searching. And Spencer has been writing those letters.

At the end of every one, a request: "Answer back, brother".
