Film which follows the fortunes of respected but obscure Canadian metal band Anvil as they record their thirteenth album and try to live out a childhood dream of rock superstardom.

At 14, Toronto school friends Steve 'Lips' Kudlow and Robb Reiner made a pact to rock together forever. Their band Anvil went on to become the 'demi-gods of Canadian metal', releasing 1982's Metal on Metal, which influenced a musical generation including Metallica, Slayer and Anthrax.

All those bands went on to sell millions of records but Anvil's career would take a different path - straight into obscurity. But Lips and Robb never gave up on their childhood dream and kept rocking, always believing that one day Anvil would taste the success that had so long eluded them.

The film follows Lips and Robb, now in their 50s, as they gear up to record their thirteenth album, This is Thirteen. Coping with increasingly impatient families, crippling mortgages and the effects of old age, they know this is their last chance to really make it.
