X marks the spot

A black-and-white cow enters the neighbourhood and is lifted into the spaceship. It appears in the cockpit with Kaylian and Kevlian, then chases them through a corridor.

The children sit in the bedroom while Kellian, in his tracksuit, camps beside a small barbecue and a green tent near a lifting bridge. He gives a paper map to a stork-like bird.

The bird carries the map over waterways and rooftops to the purple front door of the brick house. The Jet2 aircraft, green sports car and red saloon are still visible nearby.

Grandma throws a cushion at Grandad in the living room, where his model railway equipment is visible.

Curtis drives a dark grey BMW i8 with black detailing and arrives outside the house. Its raised door and interior are visible.

Curtis joins the family and examines the map with Chloe and Callum at the wooden dining table.

Kellian appears beside Dan and the red telephone-box contraption. Cables, electronics and a screen reading TELEPORTATION READY surround it.

Curtis drives Chloe and Callum in the BMW i8 across the lifting bridge to the tent.

Kellian continues talking beside Dan and the telephone-box machinery.

Curtis and the children inspect the tent, lift a floor hatch and discover a long staircase descending underground.
