When a key member of The Bureau Underground, a top-secret government agency, goes missing, Leroy, a cynical former detective, and Max, a genius `true believer' in the paranormal, are recruited to find him.

Leroy and Max take Jermaine trick-or-treating, but a demon cat infects him with a zombie-esque virus; the Bureau Underground has a busy Halloween night of paranormal activity.

Leroy romantically pursues a female cop while searching for the culprit behind a string of murders; Capt. Lafrey suspects her daughter is sneaking around behind her back with a boy.

Director Romslo puts the whole office on lockdown when a deadly amphibious creature escapes in The Bureau Underground, giving Max and Leroy only 30 minutes to eliminate the threat.

Annie accompanies Max and Leroy as they go under cover to investigate a bizarre incident at an elite country club.

Annie installs smooth-talking artificial intelligence Sam to manage the office; Max and Leroy are put to the test when Sam turns out to be evil; Max is jealous when Leroy makes a new friend.
