The Trans-Dimensional Bamboo Boat
Teenager Kathy Morgan, on a family camping holiday with her brother John and her parents Carl and Vicky, is bored. But she gets more than she could have wished for when she comes across a strange-looking craft in the bush. She gets in and fiddles with the controls, accidentally starting it up. As it starts to dematerialise, a strangely dressed man leaps in and her brother Josh arrives just in time to see his sister vanish.
