Person on Tape: Good morning, Mr. Briggs. The man you are looking at is Vincent Dean, a jazz musician who is also one of our best agents.

Good but very, very poorly timed.
7 February 2014 | by (Bradenton, Florida) – See all my reviews

"A Cube of Sugar" is a good episode of "Mission: Impossible" but it also has to be among the most poorly timed. Only one episode earlier, there was a mission that was incredibly similar--too similar. It's really odd that they didn't play these are very different dates. Both have guys held hostage in a mental hospital and they are given mind-altering drugs in order to break the prisoners! The big difference is that in "Shock" it's the IM Force doing the drugs (along with shock treatment) but in "A Cube of Sugar" it's an enemy government that is trying to break someone.

A US agent, posing as a jazz musician, has been caught and is being held in a psychiatric-like facility and is being tormented to get him to talk. What the enemy doesn't know is that one of the sugar cubes they've found on him is NOT laced with LSD but contains an important microcircuit! So the plan is to get Rollin into the same facility and then have this magician slip out of his straight jacket and inject the prisoner with a drug that makes him appear dead--so his 'grieving widow' (Cinnamon) can claim the body and help him to escape.

As I said above, it's a good episode. Just DON'T watch it right after seeing "Shock" or it will most likely tick you off or bore you because "A Cube of Sugar" is essentially a reworking of the same story--and one that isn't as good as well.
