Ruby Skye P.I.

Ruby Skye discovers that her neighbour Mrs Gooje has been the victim of the Nigerian email scam. She decides to try to get to the bottom of it. Ruby bribes her sister, Hailey to look at the email. She realises that the IP address used to send the email came from their school, the Dragon Academy, which means that the scammer could be someone they know.

Ruby notices that her best friend Griffin has a new iPhone and decides to do some detective work. Her teacher, Ms. Springer, is also acting strangely nice. Ms. Springer writes on a piece of paper then tosses it into the recycling bin. Ruby hangs back after class to go through the recycling bin when she is caught by the new janitor, Vinnie. She beats him at a game of rock, paper, scissors. The sheet of paper has scrawled pictures of hearts and flowers all over it so Ruby decides to follow Ms. Springer to see what's really going on. Turns out that her crush is even meaner than Ms. Springer. Later, at Griffin's house, Ruby notices a new TV and computer games. As Griffin plays, Ruby delves through his computer history and discovers that he has been researching the Nigerian scam.

Ruby owes Hailey a total of four hours shopping after bribing her to get the name of Ms. Springer's crush on her petition and hacking into Griffin's email account. Hailey hacks into his computer at school while Ruby distracts Vinnie with another game of rock, paper, scissors. In a series of hidden folders, Ruby discovers the email sent to Mrs. Gooje.

Ruby has a new issue: to try and persuade Griffin to give back the money without getting the police involved. While shopping, Ruby bumps into Diana, a girl at school who has been giving her a hard time. As Diana offers her shopping advice Flint Shearson comes in to distract her, leaving Diana an opportunity to plant a scarf on Ruby. Ruby chases after Flint only to find herself in trouble with the police for shoplifting.

When the police officer goes through Ruby's backpack she finds evidence against Griffin in the email scam. Griffin has his computer taken and is threatened with charges. Griffin tells Ruby via text message that he wants her out of his life.

Ruby meets Gary on the street and discovers that he has been a victim of the spam scam too, not only losing money but his lucky hat too. He last received an email that morning, which clears Griffin of the crime as he has no access to his email. After Hailey asks the class to sign her water bottle ban petition Ruby discovers that Hailey has both the means and opportunity to set up an email scam: she has everyone's email addresses!

Ruby admits she may have made a dire mistake accusing Hailey of the crime. She lacks means, motive, and opportunity. Ms. Springer, however, has the ability to access everyone's account. She overhears Ms. Springer talk to her mother on the phone about a letter. Ruby sneaks into the computer lab to find Vinnie reading her book on detective work. She searches through Ms. Springer's things and finds her letter. Assuming that the letter came from Flint, Ruby discovers that he cannot marry Ms. Springer because he does not have the money to support her. This gives Ms. Springer motive! Ruby follows Flint and overhears his phone call. He is persuaded to marry Ms Springer for her money.

Hoping to follow Flint, Ruby accidentally brings attention to herself. Running from him she bumps into Vince. He offers her protection. Hailey and Griffin are still refusing to talk to her and now she needs to stop a wedding! Diana offers to buy Hailey and Griffin ice-creams. Ruby realises that she has a lot of money lately, so it could just be her. Stealing Hailey's phone, Ruby sends a text to Griffin and uses Griffin's email account to contact Hailey, but while she waits for them Vince and Flint enter the classroom. They play rock, paper, scissors. Clearly these two know each other. Vince pulls out Gary's lucky hat and puts it on.

Realising that Vince and Flint are using Ms. Springer's class and Hailey's petition to conduct the Nigerian Spam Scam, Ruby hides under the desk to listen to their plot. Vince gives Flint the wedding ring and tells him to get to the wedding in half an hour. The door creaks. Griffin, who has been listening at the door runs away but is caught by Vince. Ruby stands up for him, but that only leaves them both trapped in a closet together with Vince standing guard outside. Ruby asks Griffin to text Hailey to warn her, but Ruby still has her phone.

Griffin reveals why he has been so cagey about his new gear: he is worried that his father is a thief. Ruby reassures him that he is not. They make up. Hailey is thrown into the closet. Ruby looks for a way out: she uses Griffin's Mentos and the soda in the closet to create a soda explosion. They escape from Vinnie but he's still after them.

Ruby, Hailey, and Griffin run away from Vinnie. They split up, Ruby leading Vinnie away from the other two. Mrs. Gooje's imaginary dog attacks Vinnie, giving her a head start. Ruby walks into Gary's ice cream shop to hide and comes across Diana. Enacting revenge for setting her up, Ruby knocks Diana's ice cream into her shirt. Vinnie, Mrs. Gooje, and Gary who sees Vinnie wearing his lucky hat chase after Ruby. She leads them through Ms. Springer's wedding, stops her from marrying Flint, and brings them to Hailey's water bottle rally. They push a water bottle mountain onto the two scammers and the police arrest them.

Ruby goes to apologize to Griffin again, but he is only concerned about his father being a thief. Griffin's Dad goes to play music with his friend and as he turns Ruby sees something familiar hanging out of his backpack. She goes to Ms. Springer's classroom to collect Hailey's petition but she's already left to mail it to City Hall. Ms. Springer thanks Ruby for her help in cancelling the wedding. Ruby stops Hailey from mailing the petition with the promise of yet another hour of shopping to discover that Griffin's Dad signed the petition without Hailey ever seeing him. Ruby drags Griffin to meet up with a clown who turns out to be his Dad. With that last mystery solved, Ruby cannot help but be intrigued by talk of a haunted library.
