The Masked Singer

CBS presents DICK VAN DYKE 98 YEARS OF MAGIC, an unforgettable special celebrating the legendary career of the iconic entertainer for his 98th birthday.

Each week one contestant will have the chance to win a cash prize if he or she can tell the difference between the good and bad singers, without ever hearing them sing a note.

We've all heard them ... the Mafia killed JFK, the government had a hand in 9/11 and the existence of aliens is the world's best-kept secret. Conspiracy theories are as old as mankind itself, and for just as long people have been taking sides. The advent of the internet provides a unique opportunity to level the playing field and give all men equal access to the facts. In April 2011, the FBI finally relented and established an online repository of files, documents and reports called "The Vault". Unsealed: Conspiracy Files is a ground breaking new show that shines a light on many of these archived case files.
