It’s summer, and Oliver and Anika have a whole new mystery on their hands – figuring out who their real dad is! But an unexpected guest and an invitation to a high-tech summer school sends them in a different direction.

Determined to get to the bottom of what’s inside the toy bunny, Anika decides to accompany Jennie to the summer school and pretend to be Sal, leaving Oliver to search through lists of potential dad suspects.

Oliver, Jasmyn and Evie head to a book signing following a lead they hope will get them some bio-dad names. Meanwhile ‘Sally’ is given a difficult initiation test by the intimidating Miss Lucas, putting her cover under strain.

Jennie and Anika hit a dead end with their investigation into the bunny’s holocode device, while the hunt for the twins’ dad reveals a new name, yet further frustrations.

The Hunters struggle to free themselves from the lockdown created by Erik’s over-zealous security system via a series of riddles in their very own Hunter Street Escape Room adventure.

Evie struggles to convince the others there’s someone else in the house, and with Erik and Kate swiftly departing for their trip, the Hunter kids are left alone with a potential threat lurking in their midst.

Anika and Jennie try to get to the bottom of the mysterious VR headsets and make a disturbing discovery. Meanwhile, Oliver, Florian and Jasmyn are in for a shock of their own when they pay a visit to Florian’s house.

Still reeling from the break-in at Florian’s, the Hunters plan another one – at the Academy. While Anika, Jasmyn and Jennie get their spy on, the boys are set to work trying to find a potential code word to unlock the holocode.

The heist at the Academy doesn’t quite go as expected and the girls discover Miss Lucas has an obsession with the Hunters. Another unexpected reveal for Daniel and Evie leaves them reeling. Can Florian be trusted?

Miss Lucas is intent on proving to Jennie and Anika that nothing suspicious is happening at the Academy. Meanwhile, Jasmyn calls Oliver for help, and the Florian situation begins to escalate beyond the Hunters control, reaching a chilling climax.

Anika is noticeably different now she’s ‘Badika’ but will the others realise there’s anything wrong? Oliver, Jasmyn and Florian skip out on their house chores to visit Orphans Inc and get an unexpected lead on the missing Jacksons.

Still under the devastating effects of Miss Lucas’s brainwashing program, Anika betrays her family by leading an operation to kidnap Baby Harry, and Florian tries to pull the wool further over Oliver and Jasmyn’s eyes. Evie, however, grows suspicious.

Anika and Florian head into the tunnels to follow Miss Lucas’s coordinates. Jennie is determined to get another crack at the supercomputer but discovers way more than she’s bargained for. Bad Anika uses the headset on Evie.

A shocked Jennie shows the others what she’s witnessed at the Academy and they come up with a plan to un-brainwash Anika. Meanwhile, Evie still can’t remember Florian, although her suspicions about him are starting to re-surface.

The gang wait with bated breath to see whether the blocker has worked on Anika, plotting how she can then act as a double agent and steal back the items she lost. Miss Lucas shares her evil plans, which have devastating implications for the Hunters.

Anika pretends to still be bad in order to steal back the holocode device from Miss Lucas. Jennie is able to unlock it revealing an eerie message from the past and a warning for the future. It’s not just the Hunters in danger, it’s the whole world.

Oliver remembers it is Dottie’s birthday and rushes to prepare a celebration for her, while Anika and Jasmyn head into the tunnels to find the missing piece of the Oscillator. The Hunters finally get to the bottom of the Jacksons’ disappearance.

Oliver’s loyalties are tested as Miss Lucas manipulates him and danger befalls Daniel. Jennie finds out some background on Miss Lucas and her bitter grudge against Erik Hunter, while Anika and Jasmyn become increasingly worried about Daniel.

With time against them, Anika and Jasmyn rush to Orphans Inc hoping to rescue Daniel and the Jacksons, while Jennie and Josh sneak into the Academy to try and find more evidence. But Evie has her own battles at home looking after the adults.

In a final epic showdown in the tunnels under Hunter House, the Hunters must stop Miss Lucas before she brainwashes the whole of Amsterdam.
