After adapting the slimy transmogrifying Wilberforces of Maurice Gee novel Under the Mountain for the small screen, scriptwriter (and future sci-fi novelist) Ken Catran returned with his own tale of kids and extraterrestrial contact. The series follows holidaying teen Gretchen (Sarah Dunn) trying to unravel the mystery of a weathervane — a "daisy rod" which seems to have otherworldly powers — and curious objects found in a tapu swamp. Backing up this girl-power sci-fi adventure are Catherine Wilkin, Roy Billing and Utu star Zac Wallace.
