Mike's been looking for love all his life without much success, but his chance finally comes when he successfully secures a date via the 'Cyber-Hearts' online dating site. His evening preparations are thrown into chaos, however, when a stranger turns up at his flat claiming to be Martin, his time-travelling son from the future.
