A home built in one day. An over ambitious goal? Not for engineer Tom Pirelli who first achieved the dream in 2006 as a response to the realities of homelessness. Today, more than 3 years later, Tom's vision has drawn in volunteers from all over North America seeking to help answer the prayers of underprivileged families in the world's poorest regions. The new Salt + Light documentary 1 Day follows one such group made up of 8 high school students from Loyola High School in Montréal who travel to Ensenada, Mexico to embark on a home building mission that would forever change their lives. In just one day, they build a home for the endearing Comacho-Gómez family who teaches them more about life than they could ever hope to learn in the classroom. From countless unexpected discoveries to witnessing the power of prayer first hand, the students share all in this moving piece that offers a glimpse into the project that is changing the world, one home at a time.
