The Earth is plagued by a series of unexplained events that occur every day at exactly 1:13 PM. On September 21 at 1:13 PM, the space shuttle Atlantis disappears from the control screens during its final flight. On September 22 at 1:13 PM, all the clocks on the planet stop. At that very moment, the Antikythera mechanism of a strange astrolabe, which no scientist has been able to activate until now, springs into action. On September 23 at 1:13 PM, the space shuttle Atlantis reappears and lands in Cape Canaveral. Onboard is only one survivor, the mission commander, amidst the dismembered bodies of his crew. On September 24 at 1:13 PM, an American submarine locates a German military submarine that disappeared sixty years earlier. The crew of a fishing trawler witnesses the hull of the Titanic rising from the sea, which sank over 100 years ago at the same spot.
