As Dani cannot go out with her friends Toby and Sam, the trio end up spending most of their time in Dani's house in her hip den hangout. Dani and her pals assume that their antics are being broadcast to the world and beyond. In fact, their zany activities are being closely observed from on high by a pair of aliens, Zarg and Zark, who are hooked on Dani's show, and who bear an uncanny resemblance to Dani and Toby. Dani faces a dilemma - she has broken her mum's favourite vase and, as she has already 'borrowed' money from Max, she is in desperate need of cash to sort out the problem. The solution might just be buried underneath the house.
