A strange brother and sister return to their former home, which is now derelict, and in the hands of a developer, their searching for their long lost mother.
I've been trying to think what this reminds me of, and I think the closest I can get, is a tales of the unexpected, it could have easily been written for that show, it has the sting in the tail, and the somewhat overly quirky characters.
The brother and sister are definitely perhaps a little overly strange, but they're both well acted characters, and both develop the story.
The ending came as a real surprise, it was well done, and could have been done over two episodes.
Boyden and Datta are both good, and made a good duo.
Good, 8/10.
