How about if a young man and a young woman, one with a pink cell phone loaded with futuristic control doodads and the other with a similar blue or silver cell phone, travel back to Ohio University October 1979, and instead of getting their pictures taken they encounter a woman who steals her pink futuristic cell phone to look up the future and finds she's overlapping in time with her 61 year old self from the year 2022? Meanwhile, the 19 year old version of Karen Louise Cole is looking for serial murderers Ted Bundy and Richard Ramirez, AKA the Phantom Prince and the Night Stalker, and has already invited them through talking to Bundy to Hell Week, which it is at that time, into visiting the OU campus. Only Ramirez shows up. Karen gets the pink future cell phone, which didn't exist in 1979, back to the other young woman. She does so by handing it to the young man. The couple from the future suddenly vanish in a rainbow-colored shower of sparks, and Karen, who is more or less a karate student, runs across the street to start searching the OU campus for Bundy and Ramirez.
