Madam Secretary‘s run is coming to an end, and when it says goodbye, the drama will do so with several esteemed guest stars — and a wedding!

In the series finale, World Cup Champion U.S. Women’s Soccer team members Crystal Dunn, Allie Long, Ashlyn Harris, and Ali Krieger visit the White House to help Elizabeth (Téa Leoni) kick off a new landmark political initiative. Also appearing in the episode alongside the athletes is acting icon Cicely Tyson as Flo Avery, who was born the day women were granted the right to vote. Tyne Daly will join brother Tim Daly on the series to play Ohio’s Senator Amy Ross, who opposes the initiative.
