In one of Project Blue Book's most challenging cases, 2 nuns, Sister Lucy and Sister Anne, report they sighted a UFO and communicated with aliens who left a cryptic message about their return. After their prolonged encounter with the star-ship on the grounds of a convent in New Mexico, Sister Lucy Ryker claims to have communicated with the aliens after she was joined by Sister Anne, who insisted on learning the identity of the beings in the craft. But they find that their legs are suddenly immobile and 2 mysterious images appear before them - a rose and fire. When they report the incident to Project Blue Book, Sister Lucy is pressured by the Archbishop to deny her claim. Then tragedy strikes when Sister Anne dies, and Sister Lucy leaves the church after she is ridiculed by her Archbishop, who insists that she publicly state that she lied about seeing the craft.
