After delivering a more personal story in 'Kid + Plane + Cable + Truck', 'MacGyver' Season 4 is turning the dial up to 11 once again with yet another high-octane race against time. In Episode 4 'Windmill + Acetone + Celluloid + Firing Pin', Angus 'Mac' MacGyver (Lucas Till) and the Phoenix Foundation are headed to Germany to deal with a blast from the past, literally.

In the upcoming episode, MacGyver will have to work double-time trying to rescue people trapped in a collapsed building while simultaneously stopping a World War II-era bomb from going off and killing everybody, the team included. It's quite a challenge but if anyone can pull it off, it's MacGyver.

We're going to assume the episode is probably set in a windmill, considering the title, and "firing pin" could be a reference to the bomb itself. Of course, right now we don't know how acetone and celluloid figure into the mix. 



 

For those who might like a quick chemistry fact, celluloid was formerly used extensively in film reels and is soluble in acetone and is a highly flammable substance on its own. Right now, we don't know how that might prove useful. But seeing our heroes make connections that we would never see is half the fun of 'MacGyver' after all.

The last episode didn't feature Codex, the mysterious organization that seems to have made it their mission to challenge MacGyver and his teammates at every turn. Hopefully, this episode might hold more clues about the organization and its true agenda. 

Here is the official synopsis for the upcoming episode: "As MacGyver works quickly to rescue survivors from a collapsed building in Germany, he discovers a new safety threat — an undetonated bomb from World War II is hidden beneath the rubble."

'MacGyver' Season 4 airs new episodes every Friday at 8 pm ET, exclusively on CBS.
