Every time she rides her bike

Every time she rides her bike she ties a fox tail to the back of it then punctures a can of paint on the frame This is because she is about to take part in a cat-and-mouse chase game The rules are simple: Lisa gets a five-second head start on her bike and when the countdown ends the group of men behind her begin their frantic pursuit If anyone manages to grab the fox tail off the bike before she reaches the finish line they win a one-million-dollar prize But if Lisa makes it to the finish line with the tail still attached the prize money is hers To shake them off Lisa rides into a pedestrian street packed with crowds But the paint leaking from the can gives away her position loud and clear so no matter where she rides the competitors quickly catch up In a moment of desperation Lisa comes up with a clever idea At full speed she rides her bike and leaps onto a truck ahead of her By the time the men reach the spot they find that the trail of paint has come to an abrupt end But they don't give up instead they scatter in all directions to search for Lisa Soon they close in on the area near the truck Fortunately the cargo on board keeps Lisa hidden from view Watching her competitors drift further and further away Lisa finally breathes easy and drops back down to the ground continuing her ride But just as she rounds a bend she spots a rider coming straight at her head-on Lisa has no choice but to turn again and ride into a residential community by the roadside Inside there is only a narrow footpath lined which severely limits her speed Just as the other rider is about to grab the tail Lisa makes a sharp sudden turn and the rider, unable to react in time, crashes into a bench and goes down After leaving the community Lisa thinks she is safe and rides along the road in a relaxed state But at that moment a pedestrian catches her eye someone who looks remarkably like her father who has been missing for many years childhood memories come flooding back Just as she loses herself in those memories a car door suddenly swings open ahead of her Watch where you're going Use your mirrors Those few seconds of distraction cause Lisa to accidentally crash into a police car ahead Since this is an illegal race even the riders who have caught up don't dare reach for the tail— they quickly turn around and flee the scene Lisa, however, is ultimately taken to the police station It is only thanks to Anna, her father's former assistant, who pays a hefty sum to bail her out that Lisa is released before long But she doesn't seem happy The pedestrian has stirred up her longing for her father Seven years ago her father disappeared in an accident and everyone assumed he was dead But Lisa has never been willing to accept this and so all these years she has been searching for him Sure enough, this day she finds a clue hidden inside a set of building blocks her father used to play with Inside are a letter and a golden key Following the directions in the letter Lisa makes her way to her father's gravestone She notices that the "R" in her father's name and instinctively reaches out to touch it it turns out to be a button that can be popped out After removing the button a keyhole is revealed inside and the golden key fits perfectly She gently turns it one full rotation and a hidden door beside the gravestone swings open automatically
