Sullen (2008)

Schmitty's (Adam Huddleston) life hasn't worked out for him. He hates his job, his car died, his girlfriend left him, and he spends his weekends drinking himself into oblivion. To cheer him up his buddy Jim (J Lalonde) drags him to a cocktail party at their pal Guy's sprawling country house, with nothing around for miles...except an abandoned cemetery. Guy (Greg Hewett) has invited everyone he knows... unfortunately that's only about 8 or 9 dudes. With no alternative but to consume brain-deadening quantities of alcohol, they drink the night away. Morning comes, and with it a crushing headache, as well as a straggler from last night's party, the irritable Mixon (John Trenter), who demands a ride home, and NOW!!!! The power is out, the phones are dead and it's just then that the boys discover they are not alone...
