A 41 year old actor plays a man who is clearly attracted to the character the 16 year actress is playing. He keeps making eyes at her. It's really creepy. She's clearly a teenager. She seems to have a crush on him, too. He leaves his shirt half way unbuttoned. The actor who plays the yeti is most likely an adult as well, and he is also attracted to her. The 41 year old character also sexually assaults the 16 year old later.
The begining and end show a scene of huge ice sheets probably falling into the ocean. I think it's stock footage. A lake is also shown, which the yeti crosses through twice to throw off people following him.
