Trailer for the documentary Thank You for Coming, which screened at Doc NYC Film Festival.
More than a decade after learning she was conceived via a sperm donor, filmmaker Sara Lamm is still on the hunt for her biological father. Using online registries and the scant clues provided by her parents, she is able to track down Jennifer, a woman sharing remarkable similarities who might just possibly be her half-sister. Working together, they become genealogical detectives, navigating ancestry databases and DNA tests as they explore the meaning and power of family in this alternately funny and bittersweet personal film.
