Ranma and Rella are investigating a client's spouse when they learn that the casino where he is losing money is a front for an arms dealing operation. Their car crashes, apparently killing both of them, but Ranma reappears after a week, only to have the gangsters try to finish him off.
Rella reappears at midnight with no memory of how she ended up naked and falling into the hotel pool (as Ranma escaped from the gangsters). She takes on a missing persons case only to discover her employer is out to murder the missing teenager, and then Ranma reappears, wearing a dress in a women's locker room.
Concerned about his missing day while Rella was in control, Ranma goes to the hospital for a check-up, but stumbles across a dying man and ends up wanted for the murder.
Dorothy witnesses the transformation and informs her mistress who goes out to eat and gets a note telling her the dish is poisoned. She spends the rest of the day looking for the antidote only to have to hand the problem over to Ranma at midnight.
Alice's organisation is after three killers known as the Mad Pig Brothers who stole information from them, so she hires Ranma then tells the Mad Pigs he's coming.
In a retrospective, Ranma meets Rella for the first time when he's hired to find out where she lives, only to discover he's pointed the way for her to be killed and he needs to save her and his best friend.
