We think we know everything about Marilyn Monroe. But the filmmakers aim to dispel this notion and try to unravel a new mystery from the star's life. Forty years after Marilyn Monroe's death, a suitcase belonging to the famous actress was auctioned in Los Angeles. It had been stored for all these years among unclaimed items in a New York storage facility. The suitcase was purchased by an eccentric and passionate collector—Princess Tenko, a Japanese magician. A well-known and popular figure in Japan, she is willing to spend vast sums to buy items such as a toothbrush, underwear, or a dress that once belonged to Norma Jean Baker.
