Nick and Vanessa Lachey host this social experiment where single men and women look for love and get engaged, all before meeting in person.

The unique dating experiment lands in Sweden as local singles seek true love and propose marriage — all before seeing each other in person.

In this one-of-a-kind social experiment, four individuals attempt to find their perfect spouse via astrological matchmaking. Their romantic adventure takes place at a retreat run by a mystical guide, the Astro Chamber. They mingle, match, date, eliminate, and eventually make the biggest decision of their lives… will they marry their match based solely on their astrological compatibility?
