The cast included William Smith as Don Carlos, James Nokes as Francisco, John Freeman as Sebastian, John Wiltshire as Antonio, George Bright as Baltazer, Cave Underhill as Guzman, Anthony Leigh as Guilion, Elizabeth Currer as Isabella and Margaret Osborne as Jacinta.
The couple have secretly exchanged private vows of love, but Julia's father then coerces her into marrying Don Francisco, an old Englishman who now lives in Spain.
Carlos announces to the group that he and Julia did not commit adultery, because their private vows meant that they were already married in the eyes of God.
In a sub-plot, Francisco's haughty daughter Isabella is supposed to marry Antonio (a friend of Carlos).
Anita Pacheco notes that 'what is immediately striking about The False Count in generic terms are the ways in which it blurs the distinctions between the camps of the cuckolding parties'.
