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