The Emerald Tablets

On the brink of suicide, an insecure grad school drop out lets himself get abducted by kooky time traveling Venusians on a mission to prevent Armageddon by rescuing Jesus H Christ and helping him find the legendary emerald tablets, but when he's cheated by his sources and abandoned by his allies, he must overcome his uncertainties to out-maneuver his rival plotters and the Romans before somebody gets crucified.
