Teasers for Marvel Entertainment's "BOOM" episode of "Agents of SHIELD" have been released recently. The first sneak peek titled "To End Inhumanity" is for Tuesday's episode.

The Superior/Anton Ivanov (Zach McGowan) - a Russian industrialist and leader of the Watchdogs - had spent the night reading the Darkhold, even if Dr. Radcliffe (John Hannah) had already instructed him not to, ComicBook said. While he was looking through it to search for a solution to eliminate the Inhuman problem, he said that the dangerous and powerful book provided him an answer: Radcliffe.

When Radcliffe learned about this, he was happy and eager to begin the first step in their plan. However, for the plan to work, they need an Inhuman, which apparently is not very easy to come by. To be able to do this, he planned on creating one with pure Terrigen Crystals.

He explained that he was able to pick up some samples during the previous year when he was working for his old benefactor. He added that his goals were the complete opposite, so he has been working to refine and grow the compound.

The previous episode shows agents Sam and Billy Koenig being hunted down to get at the Darkhold book, and only Phil Coulson and the team can save them before the clock ticks out. Now, the official synopsis of the upcoming episode of "Agents of SHIELD" says that a combustible Inhuman is hell-bent on blowing SHIELD to bits. Daisy, Mace and the rest of the team must find a way to contain the explosive Inhuman, Cosmic Book News reported. Meanwhile, Coulson and Mack come face-to-face with Radcliffe's inspiration for Aida.

The episode was written by Nora Zuckerman & Lilla Zuckerman and directed by Billy Gierhart. Season 4's "BOOM" episode will air Tuesday, February 7 at 10:00-11:00 p.m. EST on the ABC Television Network.
