Lesson Plan brings an internationally celebrated operatic contralto into the world of online teaching while her headlining stage engagements are on hold. Thought to be teaching trained singers at a prestigious conservatory, she catches her assistant in a scheduling faux pas and instead takes the Zoom stage for a community college with the same acronym – a group with little singing experience or interest in what the great diva had in mind. Intercepted by an overwhelmed school administrator who moonlights as an amateur choir director, the pair clash over teaching technique, singing and the purpose of art.
