The main character of the movie – the young guy who is called Alex. Now he very much worries about the younger brother as that dreams nightmares for a long time and fears and quite strange imaginations do not allow to live. All the matter is that he often sees monsters and therefore is afraid of a shadow. Parents, as well as Alex, perfectly understand that children at such age often think out something, dream and then trust in it. Therefore they cannot help the defenseless child in any way, and refuse to recognize their existence at all. All this causes suspicion in Alex, and he decides to correct independently this situation and to find some way out. Together with the company of friends they begin hunting for these monsters and do it in playful way. And everything was good until children did not meet the real monster and now their game accepts absolutely other turns.
