Two centuries ago the Swan sisters were accused of practicing witchcraft*. After being found guilty, rocks were tied to their feet and they were drowned for their crimes in the harbor of a little town called Sparrow. These women were not witches. Following their wrongful execution*, the three sisters returned for one month every summer to exact revenge* on the town folk of Sparrow by inhabiting the bodies of three young women before picking any number of young men to drown in the ocean. This is the legend behind this story.

Penny Talbot has lived in Sparrow her entire life on a little island just off the shores of this small town. Like everyone else in Sparrow, she is familiar with the tales of the Swan sisters and takes them very seriously. When Talbot meets a handsome boy by the name of Bo she is instantly curious about his presence in Sparrow, especially his timing. It’s Swan season in Sparrow, which means any young men to enter the town are in immediate danger of being seduced and drowned by the Swan sisters. Bo doesn’t know about it and claims to be looking for work. He asks Talbot for a job taking care of the lighthouse on her island. Talbot turns him down. The night of the Swan party (a celebration every year in Sparrow to celebrate the upcoming drownings and influx of tourism), Talbot runs into a problem, and Bo comes to help. She decides to give him a chance and offers him the job. Gradually the two become closer, but as Bo’s life becomes endangered Talbot must find a way to save him.(SD-Agencies)
