Dead Before Dawn (2012)

Casper Galloway, an overcautious boy, has become afraid of anything dangerous since the day his father died in an accident at the Occult Barn, his grandfather Horus's shop. When Horus receives a lifetime achievement award, Casper mans the shop so Horus can collect the trophy. Horus warns "no one is to come within spitting distance" of an urn kept on a high shelf topped with a skull. Horus goes on to explain that Casper's great grandfather Gilbert Galloway imprisoned a malevolent spirit inside the urn and it will curse the person that lets it out.

Charlotte, the girl Casper has a crush on, visits and he tries impressing her with a free purchase for loyal patronage to the Occult Barn. However, more of their friends arrive and make the situation worse. Casper takes down the urn to show off to Charlotte and clumsily drops it. Casper tries warning them of the danger, but they laugh at him, thinking him to be paranoid. Skeptical, they invent a curse of their own: anyone with whom they make eye contact with after 10pm (since midnight is cliche) will kill themselves and come back as a "zemon", a zombie possessed by the evil demonic spirit entrapped in the urn. The zemons spread their infection through hickeys rather than bites, and those infected kill themselves and become zemons. As an additional rule, if someone gives a zemon a French kiss, the zemon will become their slave. They are given until morning to undo the curse, or else they're cursed for eternity. However, they neglect to come up with an easier way to break the curse.

When Casper spends the entire evening preparing for the curse, his concerned mother believes him to be on drugs. Once 10 o'clock comes, Casper decides the curse is fake, makes eye-contact with his mother, and explains something happened at the Occult Barn, ending her worries. At a football game, players and cheerleaders begin killing themselves, and Casper and his friends realize the curse they made up has come true. Casper finds his mother dropped a toaster into the bathtub with her, and he flees when she comes back a zemon. Luckily, she's hit by a car, but Casper accidentally makes eye-contact with a passenger, forcing him to run again. He bumps into his best friend Becky, whose boyfriend had turned into a zemon earlier that night, and she says she now believes that the curse is coming true and that Casper was right. The two of them realize that the others are still at the football game and rush to their rescue. Once they arrive, Casper and Becky see the field covered with the bodies of the game's attendees and their friends are the only ones standing. The zemons awaken shortly after and chase down the group. They track down Casper's friend Seth, another member of the gang, to warn him about the curse. Seth, who had ignored the curse, reveals to the others that he had made eye-contact with everyone he met that night, thus speeding things up. The zemons manage to catch up to the group and attempt to attack them in Seth's house, but Casper and his friends escape in Seth's Winnebago.

Everyone plans to search the Occult Barn's books for the way to break the curse. Horus returns, horrified to learn of the idiocy that occurred in his absence. Before he can explain how to undo the curse, he succumbs to it and jams his trophy into his skull; however, he tells them they have to dig. They retrieve the items needed to seal the spirit again: the ashes from the previous urn (which Casper had stored in his backpack), a human skull (one of which, according to Dazzle, is in the anthropology classroom at their college), a heart (which they dissect from a toad), an urn (later replaced by one of Seth's mugs after Dazzle succumbs to the zemon curse and breaks it), and the watch belonging to Horus's father (which they have to get out of his grave). However, most of the group is killed by the zemons along the way (or in Seth's case, gets knocked unconscious), leaving only Casper and Charlotte. A final line in the instructions reveals that Casper must give his life to undo the curse. He sets off a grenade, ready to die, but instead time rewinds to the moment right before the urn broke; everyone retains memory of what happened, ensuring they don't cause another curse.

When Casper and Charlotte graduate, they visit Horus and explain that they wish to become Occult Barn employees to pay for their new place. Overjoyed, Horus decides to take his first vacation ever; his attire suggests, he is going to Hawaii. After he leaves, the couple make out and accidentally knock down the urn. Horrified, they state, "We're so dead."
