An aspiring opera singer herself, the daughter summons up the courage to ask to be her mother's understudy.  When her mother callously dismisses the suggestion, she snaps and starts mulling the ultimate revenge, igniting a cut-throat battle of wills.

Silver, whose previous credits include Thirst Street, Uncertain Terms , is a regular on the festival circuit with his films previously playing New York Film Festival, Venice, Tribeca, Mar del Plata, AFI and Locarno among others. He also co-wrote the screenplay with C. Mason Wells.
