The tight-knit neighbors on Arthur Avenue have proudly lit Christmas luminaries for 40 years, but that long-standing tradition is cancelled this year when Matt Norman (Ty Wood), a teenage boy in the neighborhood, is hospitalized in desperate need of a heart transplant. As his parents Ann (Teri Polo) and Mike (Paul Essiembre) anxiously pray by his bedside, a donor is found, while in Detroit, a mother (Tess Harper) is in anguish at her own son’s bedside. When Matt's neighbors decide to honor him in the best way they know how, they just might help save his life.

When his parents, Ann and Mike, pray for a donor on a stormy night, the neighbors suddenly realize their luminaries could have a deeper purpose.
