Two men, together, on the edge of heaven. In a strange restaurant, two American giants who revere each other, Groucho Marx and T.S. Eliot, meet for dinner. Both in their own ways great defiant spirits, they create magic and anarchy, revealing secrets and sorrows. The evening is presided over by the Proprietor, who seems to control the workings of the universe. Or does she? In Dinner With Groucho all is revealed. Or nearly so.
