Following on from Inhabitant Gumm, Leader Gumm is a ‘midquel’ that significantly expands a single scene from the original film into it’s own story.  Staying true to the flashback and unreliable narrator approach of the first film, Leader Gumm follows the attempt by film maker Denham Armstrong to make a documentary about the appointment of Randolph Gumm to Vizier Ordinary. 

Preferring to edit and work the camera, Armstrong engages Vinia Darrow as his interviewer.  Unlike the original, the sequel initially follows the documenter character more closely than Gumm as he and Darrow work their way into Gumm’s inner circle collecting anecdotes about Gumm as they go. 

Finally obtaining an interview, Gumm is taken with Darrow and they begin an affair, Darrow abandons Armstrong while Gumm separates from his long-time partner.  Gumm then uses his influence to promote Darrow as a major film star, beyond what her talents can sustain as she’s essentially a journalist.  Miserable, she runs back to Armstrong who has been collecting incriminating evidence about Gumm. 

Staying true to the unreliable narrator trope, the film has several different endings, with Armstrong and Darrow variously forming a romance, acrimoniously going their own ways before one or the other is killed, dying in an accident or dying on the orders of Gumm or by his direct hand.
