New York City, a quiet summer night, June 1950, but the tranquility is about to be shattered when a dazed, confused and strangely dressed man is hit by a car and killed on the spot in what appears to be another fatality involving an inebriated drunk.

But upon retrieving the body, the NYPD realized that the case was far more complicated, they were faced with an unexplained incident that remains to this day.

The body was taken to the New York morgue, but it could not be identified; he was a man with an old-fashioned moustache and Victorian clothes last seen in the 1870s.

In his strange clothing was found a wallet containing notes and coins long since withdrawn from circulation, a coupon for a five-penny beer at a tavern that no one has been able to locate, and a receipt for the washing and care of a horse and carriage in a non-existent stable.

Amidst all this paraphernalia, a single clue, rather mysterious, turned up: several business cards in the name of Rudolf Fenz, a name that did not appear in any of the city's archives or records, so the body remained unidentified.

A young detective, Hubert Rin, took over the case. He searched every possible corner for any clue as to the identity of the man until he came across one Rudolf Fenz, Jr, by then deceased. His widow was still alive.

Determined to unravel the truth, Rin questioned the widow. But what he learnt was even more horrifying and only increased his doubts about the case. The widow told him that her late husband had once told her about her father's disappearance: he had gone out for a smoke one night and had not returned.

Rin went back to the Department of Missing Persons and, digging through old archives, found an unsolved case from 1876 when a man had disappeared without a trace on the outskirts of his estate that matched the widow's story. The archive file also contained an old portrait of the missing man, and it was none other than the dead man lying on a table in the city morgue, it was Rudolf Fenz himself.

What ultimately happened in New York City in 1950? Was Fenz an accidental traveller, caught in a tear in the very fabric of space-time? That will forever remain a mystery.
