Mission: Impossible (1966)

Season 6: Episode 2

Kroll and Stevens run the Northeast Syndicate and the IMF must bring them down. In '37 the two of them killed a rival mobster, hid the body, and killed the witnesses, so the IMF needs to get Kroll to lead them to the remains. They grab Kroll, drug him up, and cosmetically alter him to look like he was in '37. Then they dump him on a Hollywood set and convince him through incredibly elaborate means he is in 1937 on the day of the murder and the rest of his life is a dream. Overwhelmed by the sheer amount of detail, Kroll and ""Stevens"" reenact the murder at a cafe, which gives them the location so that Barney and Willy can find the real body in the real cafe's basement. The IMF fade away, leaving a reaging Kroll to confront his partner as he flees the 1937 New York set and wanders into an adjacent Old West street.
