Victoria Melies is one of the most beautiful women living in postwar Europe. She lives a life of privilege, and few people suspect that she works as a spy for MI6 under the code name: Evangeline. On her way to the Nuremburg Trials, an assassin's bullet finds her before she can testify. She's immediately transported to the Pearly Gates where Saint Peter insists on calling her by her code name and assigns her to an eternity in Purgatory. But that just won't do for the elegant operative, who demands that she be allowed to avenge her untimely death. Evangeline soon finds herself in New York City, where she is incensed to see her old nemesis, Bunny Stanton, is alive and kicking and masquerading as a British peer. The spectral spy believes Bunny is involved in a plot to assassinate Harry S. Truman and tries to protect the American president. However, Evangeline quickly discovers being a ghost has its limitations, and an afterlife handbook filled with regulations could land Evangeline on the road to hell because of her good intentions.
