In her battle to stay sober, Cheyenne begins using pills that induce severe nausea if she consumes alcohol. At the same time, Reba organizes a gathering for her real estate clients, prompting Van and Cheyenne to scramble to prevent Reba from drinking after she mistakenly ingests one of Cheyenne's pills, believing it to be a vitamin. Meanwhile, former smokers Brock and Barbra Jean attempt to educate Kyra and Jake about the perils of smoking, yet Brock can't resist the temptation and sneaks a smoke behind their backs.
