Alison (Joanne Samuel) is an Australian girl on the verge of celebrating her 19th birthday. A few days before the ceremony, Alison is visited by the ghost of her father. She is warned to leave her home immediately, lest evil befall her on her natal day. The plot contrives to have Alison be forced to return home just before the fatal hour, and you can take it from there. Filmed in 1979, Alison's Birthday was released in 1984.
