Angie, a photographer from Sacramento who's never left her hometown, embarks on a tour with Billie, capturing more than just images. Like Moon River's dream of "two drifters off to see the world," Angie's journey becomes one of wandering and wonder-navigating desire, uncertainty, and the pull of places and people that feel like home. She must decide whether to nurture this connection or let it drift away, like a river carrying her toward the unknown.
