Journey around the world in search of what it means to love one another. First, in western Pennsylvania, Ian and Larissa Murphy are two evangelical Christians who fell in love during college. Ten months into their relationship, Ian suffered a traumatic brain injury, dramatically changing their relationship while also showing them what it means to love unconditionally. Next, we meet Rena Greenberg and Yermi Udkoff of Brooklyn, New York, as they prepare to marry in the Hasidic faith, which states that every person is born with one half of a soul and that only through marriage can the two souls reunite with each other. On the other side of the world, former professional skateboarder Jordan Richter, from northern California, is embarking on the hajj, a pilgrimage that is one of the five tenets of his adopted religion, Islam. By joining millions of pilgrims in Mecca, Saudi Arabia, Jordan hopes to make peace with his past and cement a promising future. Finally, two Nigerian leaders who were former enemies 20 years ago, Christian Pastor James Wuye and Muslim Imam Muhammad Ashafa, come together to reconcile and to honor one of the most sacred teachings at the heart of both their faiths: Love your enemies.
