A genius who believes in the paranormal is partnered up with a cynical former detective after they are recruited by a top secret government agency.

With the encouragement of Max, Leroy romantically pursues a female cop, while they work on-site at a local resort. As the pair search for the culprit behind a string of murders, Captain Lafrey has Annie and Barry investigate her daughter, who may be sneaking behind her back with a boy.

LaFrey's boss, 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. The creature's first victim is everyone's favorite coworker, Bob. Unbeknownst to the team, the Sparkletts water boy is locked in the building with them, as well. Amidst the chaos, Leroy starts to suspect that Annie has a crush on Max.

When Max and Leroy investigate a bizarre incident at an elite country club, they both get a little too invested in their covers and find themselves at odds. Also, Annie accompanies them on the mission, as she frequented many country clubs in her youth.

While Captain Lafrey is out, Annie installs a smooth-talking Artificial Intelligence, "Sam," to manage the office, but Max and Leroy are put to the test when "Sam" turns out to be an evil and powerful force trying to take down the Bureau Underground. All the while, Max is jealous when Leroy makes a new friend.

When a pair of smug actors, Chaz and Jared, from the ghost-hunting show "Ghost Studz," accidentally stumble upon real paranormal activity, Max and Leroy must go undercover on set at an abandoned mental hospital to save them. Leroy resents the "perks" the actors get with their fame, realizing he and Max will never enjoy the same benefits working in a top-secret bureau. Meanwhile, Barry demands some perks of his own.

When a young girl goes missing at a haunted hayride, Max and Leroy go undercover to determine if it was a paranormal act or just a publicity stunt. Meanwhile, Barry brainstorms ways to "bro-bond" with Max and Leroy.

Max and Leroy invite Annie to tag along on their next case, as she is an expert on the killer creature they are trying to find, but Max's survival skills are put to the test when they lose their way in the woods. Back at The Bureau Underground, Barry proves himself an asset in solving Captain LaFrey's dating struggles.

When new cases become few and far between at the Bureau, Max obsesses over his multiverse theory and Leroy grows restless - until they discover a suspicious wire in the office that they think might be a secret surveillance system. They enlist the whole team to help uncover its source. Meanwhile, a customer arrives at the Bureau's facade looking to purchase wire coat hangers and everyone must take turns distracting him from the chaos below.

Everyone, including Captain LaFrey, is surprised and alarmed when The Bureau Underground is assigned a new captain, Merv Minette. Minette doesn't seem thrilled with his new post either, and halts Max and Leroy's investigation of the suspicious wire.

Leroy brings in a psychic to help The Bureau figure out who bugged their office. Although he and the rest of the team are determined to make something of the findings - in order to reclaim the office from Merv - Max refuses to give in to the superstitions.

When an article is published revealing The Bureau Underground to the public, Merv asks Leroy to interrogate his coworkers to find out who may have leaked the information. Meanwhile, Max's parents arrive at the Bureau to express their concern about his career choice, and Ava gets closer to solving the mystery of who bugged the office.

Leroy and Max spot a possible UFO. However, as they are looking at it, Leroy drops a big bomb on Max that steals the show. Meanwhile, Captain Lafrey digs deeper into the mystery suspect who has been targeting The Bureau Underground, and newcomer Merv is forced to confront some office drama.

The Bureau Underground struggles to be taken seriously while forced to share a case both with the FBI and the FAA. Disheartened by the lack of respect, the team turns to Merv who offers very little support. Meanwhile, an unlikely relationship forms and Max makes a shocking discovery.

While trying to prove their worth to Captain LaFrey and the rest of The Bureau Underground, Leroy and Max finally have a lead on the whereabouts of Agent Checker. Leroy finds himself in the odd position of being the believer when Max loses faith that they have what it takes.
