Los Angeles, 1983. A storm is coming and it's name is crack. Snowfall is a one-hour drama set against the infancy of the crack cocaine epidemic and it's ultimate radical impact on the culture as we know it. The story follows three characters on a violent collision course: Franklin Saint, young street entrepreneur on a quest for power; Gustavo "El Oso" Zapata, a Mexican wrestler caught up in a power struggle within a crime family; Teddy McDonald, a CIA operative running from a dark past who begins an off-book operation to fund the Nicaraguan Contras and Lucia Villanueva, the self-possessed daughter of a Mexican crime lord.
