The USS Enterprise was thrown from 2266 backwards to July, 1969. They didn't realize they were back in time when they entered Earth's atmosphere, so were detected as an unidentified flying object. The USAF sent a plane to investigate. When the plane cracked up in the Enterprise's tractor beam. They beamed aboard pilot Captain Christopher (Roger Perry) before his plane was fully destroyed. This created a problem as he was exposed to information about the future, but he still needed to be returned due to the importance of his offspring. The computer (voiced by Majel Barrett) started acting up by pouting, flirting, giggling and calling Captain Kirk (William Shatner) "Dear".
