Sam is on a sleepover at Dani's so she can revise for an important exam in peace - unfortunately this doesn't help Dani with her preparations for her Grease auditions. And with Ben on sleepover to redress the girl/boy balance, everyone is getting restless, and nobody is getting much sleep. Meanwhile, all of the action is being observed from on high by the aliens from outer space...

Toby and Dani are set to enter the Utterly Go Dancing heats, but when Dani takes a fall, she is left unable to remember any of the moves... or anything, for that matter, even her own name. Max is especially worried - how will he get his favourite CD back if Dani cannot remember the combination to the safe she locked it in?
