Marla Darland is blessed with the voice of an angel, a singing legend. But when her agent, Marty Starr, finds his agency in trouble, he concocts a sinister plot to bring up her record sales. Amazed at the posthumous record sales of Elvis and Jimi Hendrix, Marty becomes determined to arrange a similar fate for Marla, staging the perfect tragic demise. But he didn't count on Marla not being quite ready to go.
Unfortunately the movie Bring Me the Head of Mavis Davis is not yet available on HBO Max.
