Sisters Emma and Chantal are worlds apart. Emma is self-conscious, angry at the world and unsure of which path to take in life. She dreams of starting a band (which will be 73% metal and 2% jazz fusion!) with her best friend Gary, who secretly has a crush on her. On the other hand, her twin sister Chantal is beautiful, confident, and knows exactly where her life is headed. When their parents go away, their simmering sibling rivalry threatens to boil over as they try out new versions of themselves and compete for the affections of the same guy. Metal Heart is a coming of age comedy about family and growing up which is laugh-out-loud funny but also poignant, sophisticated and wise.
