Every other marriage in the UK ends in divorce.
Mike and Alanna got married 6 months ago, and have set out from Alaska to head to Patagonia on a Ural Tourist T motorbike and sidecar, to find out how to stay together for life. On the way, they are meeting couples to get their love stories and advice on what it takes to go the distance. In addition to this, they have met with various internationally renowned scientists who believe they can pinpoint the scientific secrets of love - and they've put their own love to the test (brain-scans, DNA tests, heart-rate monitors, etc). Only when they get to the end of thew road will they find out the predictions of these scientists. And if the findings suggest they will stay together, then they will renew their vows in the church at the end of the world.
As they travel south, they are meeting couples who embody the stories of the places which we are travelling through. In Alaska alone they have met a Russian Old Believers couple from the Kenai Peninsula living in the old tradition, a hippy couple in Girdwood, a homestead couple near Fairbanks, a former national downhill skier, a young urban couple in Anchorage and a Native Alaskan couple who have been married for 32 years, a trapper in Fairbanks, an Iditerod musher, and in Dawson City, they met a goldminer of 30 years (married for 64 years!). They attended a wedding on De Courcy island of a local Vancouver artist, and met with a gay couple who adopted a son, in Vancouver. Each of these couples has their own unique take on love, what makes relationships work - and the kind of things we can do and to go the distance.
