In the next episode of "Ghosted," the Bureau Underground goes on emergency lockdown when a deadly amphibious creature escapes from its cell.

The trailer for the upcoming installment titled "Lockdown" was released just recently and showed the headquarters on lockdown. Everyone on the team is on the hunt for a dangerous amphibious creature that escaped from its cell. Leroy Wright (Craig Robinson) and Annie (Amber Stevens West) pair up with their guns in hand while Max Jennifer (Adam Scott) and Barry Shaw (Adeel Akhtar) search on a different level. All of a sudden, a corpse pops up in front of them, which sends them screaming.

The corpse happens to be the Bureau's favorite co-worker Bob (Beck Bennett) who apparently is the first victim of the hideous monster. Earlier in the day, he bought several boxes of donuts for the Bureau to enjoy. Ironically, he is the first one to go in the lockdown. The agents are on borrowed time as they must capture the beast as soon as possible. Annie says chillingly, "If we don't kill this thing in the next 30 minutes, everything gets incinerated." It remains to be seen if they will be able to kill the monster and if there will be any more casualties.

In the last episode, Wright and Jennifer battled Officer Natalie (Megalyn Echikunwoke), a succubus who killed her victims by taking their hearts out without leaving a trace. It turned out that the policewoman Wright was having a date with was actually the monster. Jennifer was able to figure it out just in time and save his partner from the clutches of the evil creature. Natalie jumped out of the balcony and fell to the ground but mysteriously disappeared.

"Ghosted" season 1 episode 4 will air on Sunday, Oct. 22 at 8:30 p.m. EDT on Fox.
