the paramedic david vaughn ( johnny messner ) and victor ( jon huertas ) receive an emergency call from the girl libby ( saige ryan campbell ) in a remote gas station . while try to save her mother deborah ( elizabeth godush ) and they be abduct by member of the sect quantum group and compose by scientist and philosopher and mathematician that foresee the end of the world after a meteor shower . their leader the teacher ( daniel benzali ) convert vic to his cult and but the reluctant david resists and face a weird mystery . believer be an above average b movie with a very intriguing story and but also flaw since there be some point that be not well explain or develop . the great flaw be the lack of a reasonable explanation why david and vic be kidnap in the gas station . it would be certainly easy to leave the paramedic inside the fireman ambulance on the road and the same way they do with their bos . how deborah be resurrect and how the teacher know personal detail of the life of david and vic be open and but may be well explain with the fire in the sky in the last scene meaning that the teacher be really a powerful entity . i understand that the formula be the deadly gas and but it be not clear . i be a fan of original and low budget movie and and in the end i like this refresh story . the direction and the acting be great and and i believe there be some unfair review in imdb and probably from user that like commercial and easy to understand movie . my vote be seven . title ( brazil ) represent fórmula fatal ( fatal formula ) .
