Things will heat up after a massive explosion rocks the bayou when "The Originals" returns with an all-new episode on Tuesday.

From the looks of the official trailer for Episode 19, "An Unblinking Death," the next installment will be quite intense as Cami will make a desperate attempt to save Father Kieran, who is hexed and facing an imminent death. She will turn to a drastic, unconventional treatment to help her uncle; however, things won't work in her favor, warns WetPaint.

A huge explosion will take place at the werewolves' compound down by the bayou causing an alarming number of deaths and injuries. After Elijah witnesses the "horrific explosion" that will cause unrest between the many factions of New Orleans, he will team up with Jackson to help out in the aftermath of the tragedy. In turn, Hayley will get some free time and discover a shocking detail about her family.

In one clip from the trailer, Father Kieran seems to be losing his mind and he says, "This city is full of monsters." Yet, despite the fact that the hex is taking a toll on Kieran, Klaus remains nonchalant about the situation and casually says, "Well, isn't this a gruesome little scene." In response, Cami pleads for Klaus to show him mercy, saying, "He's dying, Klaus, this might be the only chance he's got." However, Klaus coldly replies, saying, "I think you need to prepare yourself. This story does not end well."

The CW also released a preview video from the upcoming episode featuring Klaus, who is up to his usual tricks, and Elijah, who is making things difficult for him to locate their mother's grimoire.

According to Dread Central, the synopsis for the April 22 episode states:

"Desperate to help Kieran, Cami insists on an unconventional treatment, but her good intentions lead Kieran to a violent episode. After Klaus (Joseph Morgan) and Elijah disagree over the best way to handle the Crescent Wolves, Elijah makes a trip to the bayou, where he is witness to a horrific explosion that only adds to the hatred and mistrust among the communities. While Jackson and Elijah work to save the wounded, Hayley learns a surprising piece of her family history from Marcel (Charles Michael Davis)."

"The Originals" S1E19, "An Unblinking Death," airs Tuesday, April 22 at 8 p.m. EDT on the CW.
