As tensions at Orbit HQ reach breaking point, Tilda must outsmart her mum to help Ginny's family to escape, while Ginny fights for the life she wants on Earth.

Feeling responsible for Ginny's capture, Tilda struggles to see how she can save her friend. With help from Kiara and Ruby, can she find the strength to pull off a rescue mission?

The Brighthawks hide Ginny's family as Orbit search camp, friendships are tested, and the camp is locked down. Meanwhile, Ruby and Oz discover the spaceship has been tampered with.

Tilda and Ginny race to Brighthawk Camp with aliens in pursuit, while Kiara rallies the troops for battle - can the Brighthawks defend their camp against aliens?

As Ginny races to rescue Tilda, the Brighthawks at camp brace for an alien attack unaware that Orbit's latest containment measures may put them all in grave danger.

Pippa, Kiara, and Ruby race to call for help, Tilda is trapped aboard the spaceship, and Ginny faces a tough choice, all while Brighthawk camp waits out the alien threat.

Everyone is trapped, the Brighthawks back at camp are defenceless, and any one of the girls Ruby is trapped with could be an alien!

When Orbit's plan moves too slowly, Tilda takes charge and teams up with an unlikely ally. But shapeshifting aliens and hidden traps make her mission a lot more complicated. 

Tilda is determined to get back to her perfect camp plan and stop Ginny from leaving. Meanwhile, Ruby is desperate to get the Brighthawks thrown off camp and safely away from the aliens. 

Best friends Tilda, Kiara, Ruby and Ginny are the host troop at Brighthawk Camp, but they are about to discover that some attendees have come from much, much further afield!
