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.
Schoolteacher Elizabeth and Constable Jack's relationship starts to heat up as they are forced to spend more time with each other. They especially bond in the wake of their shocking arrest of widowed mother Cat Montgomery.
Elizabeth takes Opal in while her parents are away; a newcomer to Hope Valley has some insight into Carson Shepherd's mysterious past; an unlikely turn of events puts Cody in harm's way.
