When Richard Marlow buys a taxidermy hare from an old antiques shop, little does he realise it contains the soul of the sinister and immortal warlock of Russian folklore, Koschei the Deathless. Soon, Koschei himself turns up, demanding his soul be returned to him - on the very weekend that Richard's girlfriend, Becky, has invited her mother to stay. Can Richard negotiate a tricky social situation whilst simultaneously thwarting the malevolent sorcerer?
