Frozen is a 2005 British psychological thriller film directed by Juliet McKoen.
Set in Fleetwood, on the Fylde coast, in North West England, it was filmed in and around the town and also on location in Scotland and Sweden.
It is a tale that has the viewer undecided whether it is a ghost story or a murder mystery right until the final climactic moments.
The film is set two years after the disappearance of Kath Swarbrick's older sister, Annie.
She is spurred on when she discovers that she has recurring visions of Annie in an otherworldly landscape, which is actually the estuary of the River Wyre in Morecambe Bay, after visiting the last known location of her sister.
