Spoiled socialite and notorious practical joker Melanie Daniels is shopping in a San Francisco pet store when she meets Mitch Brenner, who is looking to buy a pair of love birds for his young sister's birthday; he recognizes Melanie but pretends to mistake her for an assistant. She decides to get her own back by buying the birds and driving up to the quiet coastal town of Bodega Bay, where Mitch spends his weekends with his sister and mother. Shortly after she arrives, Melanie is attacked by a gull, but this is just the start of a series of attacks by an increasing number of birds.—Col Needham
