When the Professor tells Tim about a legendary supernova with mysterious powers that is set to appear in the night sky any day now, Tim knows he'll finally get the dog he's always wanted.

Jamie (Shimon Moore) is a typical teenager living the good life: a popular lad, he has a part-time job, is on the footy team and is the lead guitarist in a rock band. But all this is threatened when his mum (Celine O'Leary) announces that she has a new job as head scientist at a marine research base. Forced to uproot and move to a remote island, Jamie soon discovers that all is not as it seems. He begins to notice changes to his body - scales and webbed fingers - things beyond the explanation of teenage puberty.  Changes which suggest that he is somehow connected to a legendary line of Selkies - a magical people from ancient Scotland who have the power to change into seals.
