Los Angeles has been overtaken by a virus known as Sudden Death Syndrome, a disease that causes its victim to die suddenly and has only one symptom... spontaneously breaking into well-choreographed song and dance.

The Sound of Music Live! is a television special that was originally broadcast by NBC on December 5, 2013. Produced by Craig Zadan and Neil Meron, the special was an adaptation of Rodgers and Hammerstein's Broadway musical The Sound of Music, starring country singer Carrie Underwood as Maria von Trapp, performed and televised live from Grumman Studios in Bethpage, New York. Meron felt that if the telecast were successful, the concept could become "another kind of entertainment that can exist on TV." By her request, Underwood's casting as Maria was personally endorsed by Julie Andrews, who starred in the 1965 film.
