Esta serie, fiel reflejo de cualquier grupo de amigos de hoy en día, narra la historia de dos matrimonios y tres solteros de Philadelphia. Como la vida real, Treinta y tantos recoge los problemas cotidianos de Michael y Elliot en la importante agencia publicitaria en la que trabajan; de Nancy y sus sueños como artista; de la fotógrafa Melissa y su complejo de Peter Pan; de la dolorosa separación de Elliot y Nancy e incluso del sufrimiento de sus dos hijos. Un claro referente en las series de los años 80.
