In 1983 Thomas and his colleague Kirk are doctoral students at the university and are conducting research into extraterrestrial signals following the path laid out by the SETI project. One evening, after months of waiting, a signal is picked up by the lab's equipment, but it is too disturbed and incomplete to be deciphered. Thirty years later, in 2013, on the very night of the anniversary of that extraordinary yet ridiculed event by the faculty, when Thomas has retired to live in a small provincial observatory, a message, the same as then, is picked up by the equipment again.
