Project Mc²

Midnight nears on New Year's Eve and McKeyla and Adrienne have a mission: Stop HAVOC before it stops the countdown!

New girl and teen spy McKeyla stirs up suspicions in classmates Adrienne, Bryden and Camryn, causing them to do some investigative work of their own.

McKeyla investigates a threat to the prince's space mission while Adrienne, Bryden and Camryn stumble through proving their spy skills.

The girls band together in science and friendship. Will they be able to save the prince's space launch in time and become official NOV8 agents?

The four girls are demoted back to basics after they make a big deal out of saving the prince in the previous season. They are not allowed on any mission, even as a suspicious figure, Carson Lazarus, a criminal mastermind, is released from jail. Soon after, a figure who calls themselves "Retro" causes all technology to malfunction and glitch in Maywood Glen.

The Quail allows the four girls to figure out this case. McKeyla becomes increasingly suspicious of Kyle, but soon dismisses the idea of him being Retro just because he knew she liked fro-yo and was wearing a black hoodie, very much like the one Retro wears. They also suspect Devon D'Marco, a troublemaker, as she spray-paints handcuffs on a picture of a drone on a poster about the upcoming launch. All four girls except Bry, who has to babysit, make ways to get detention on Saturday with Devon. Bry runs a vocal recognition as Cam and Adri confront the troublemaker and McKeyla looks through her bag. Devon is proven to be innocent, just using the school's 3D printer to make skulls for her nana's birthday.

When a new point of evidence involving HAVOC points to Carson Lazarus, Adrienne and Bryden comb through her trash looking for clues.

The Falcon tasks the girls with investigating a string of robberies, and EDM band EliTe returns to Maywood Glen to perform a surprise concert

While Bry and Cam do some sleuthing at rehearsal, Adri and Ember create a gummy bear tracking device to help McKeyla find Maddy.

When a nightmare about Maddy leaves her reeling, McKeyla comes clean to the Falcon. Bry and Cam kill it at auditions and zero in on a new suspect.

The girls visit NOV8's amazing headquarters, where the Quail gives them a new mission involving an old friend. But something strange is afoot.

The girls try to stop an intruder from stealing a prototype from Space Inc. When things go awry, McKeyla begins to doubt her sleuthing skills.

McKeyla, Bryden and Adrienne discover a dark side to the nanotechnology prototype. Cam and Ember make a brainy new friend at Destination Mars Camp.

McKeyla homes in on a surprising new suspect: Camryn's dad! Meanwhile, Ember and Cam wonder if fellow camper Gordon is up to something.

The girls act fast and use their skills to name a suspect when someone threatens to sabotage a state-of-the-art urban development.

A new theory emerges as the girls turn their attention to the school dance -- and having dinner at Bobby Stone's cutting-edge "smart" home.

A familiar face from McKeyla's past steps up to help as her family connections to the case grow clearer. And "Bry-ence"? Well, it's bigger than ever.
