Based on the relationship between Leonard Cohen and Marianne Ihlen, follows two lonely people falling in love while they are still trying to discover who they are.

So Long Marianne is real; human and intimate, lung-busting, gut-wrenching, heart-breaking love story. Though it's a story looking back at extraordinary lives, it's more than that; much more. It's a story of youth, searching and finding meaning in life; a story of expression, the sacrifices life forces you to make, and purity of love and of voice. The story of two very specific normal people.
