Threshold

While a security leak threatens to put the Threshold plan in jeopardy, Molly fears that residents in a small Rhode Island town may have been infected by the alien signal after several people reported having disturbing dreams about trees made of glass. The leak is brought to Molly's attention when a newspaper article appears that vaguely mentions Threshold. Unfortunately, the article gets a meddling senator's attention and he insists on being included in the project.

Molly travels to Indiana after a Threshold agent who was watching the boyhood home of an infected Big Horn crewman disappears. While she's there Molly learns that one of the town's ministers may be infected. The pastor claims to have seen visions of a glass sea and is warning his congregation to prepare for the end of the world. Back in Washington, D.C., Baylock leads an effort to locate the sunken Big Horn and raise it to the surface for study.

Three women in the D.C. area come to the attention of Molly and her team when an artist beheads her husband, an oil billionaire's wife attacks a bank teller, and an attorney mutates and explodes on a street corner. The investigations reveal that all three were infected by the alien signal from a startling and unsettling source. In other events, Molly meets with the new national security advisor, who will oversee the Threshold project.
