On the outskirts of Dublin City, a young couple’s relationship hangs by a thread. Isolated and stressed, disputes have turned physical - leaving Karen in a poor state of mental health and Philip wanting an escape. They decide to go on a drive and head for Karen’s favourite place as a child, the Wicklow Mountains.
However, a simple oversight leaves them both stranded with no fuel and a blizzard due.
With no other choice, Philip heads off in search of help in the nearest town, leaving his pregnant fiancé alone. With Philip gone and the inevitability of a snow storm looming, Karen must battle against her plagued mind and the elements. But deep in the mountains, a hidden family secret may be the key to her survival.
