Watched this old movie a couple of years back in colour about a young female reporter hired to assist one half of a famous duo to write an autobiography but ended up sleeping with the other guy. In the middle of this all it is revealed that the duo had killed a woman years back and sent her on with their luggage while on tour. There is also a scene where she is drugged and filmed then blackmailed so she does not reveal what she knows. I’m dying of curiosity trying to recall the show and would appreciate any help!
