A sneak peek look at episode 9 of "Pretty Little Liars" shows Hanna going head-to-head with Alison over her latest dangerous stunt. ABC Family

Happy “Pretty Little Liars” day! Episode 9 of the hit ABC Family series airs on Tuesday, and showrunner Marlene King posted a special message for viewers about “March of Crimes”:

“Sh*t goes down tonight,” King shared on her Instagram page. “Don’t miss it. #PrettyLittleLiarsDay.”

As we previously reported, Hanna will be spiraling out of control in “March of Crimes.” Spencer, Aria, Emily and Alison have watched Hanna become reckless and irritated over the past couple of weeks. But their own problems prevented them from stepping in – until now. Hanna will get so bad in episode 9 of “Pretty Little Liars” that the girls will no longer be able to “stand by and watch Hanna self-destruct.”

Hanna won’t be the only one with a problem. With Ella’s wedding rapidly approaching, Aria’s worried that Hanna may have been right about Zach’s infidelity. But will she have time to uncover the truth?

Meanwhile, “Pretty Little Liars” viewers can look forward to some Noel Kahn scoop as Emily digs up dirt on the shady teen and his link to Alison. Spencer, on the other hand, will make a “surprising discovery at the eye doctor.”

Can’t wait for the drama to unfold? Check out four juicy sneak peek videos from episode 9, “March of Crimes”:

Sneak Peek #1

Caleb hasn’t been the best influence on Hanna in the past few weeks, but the old Caleb appears to have resurfaced in this sneak peek video clip of episode 9. When Hanna storms into his house and grabs a beer, he can immediately sense that something is wrong. But Hanna’s not willing to talk about it. When he finally gets her to open up, Hanna reveals that she doesn’t want to attend Ella’s party – and it’s all because Zach’s a “sleaze.”

Hanna relays the entire story of how Zach slipped her his number and wanted to meet up – and Caleb doesn’t look pleased with this information.

Sneak Peek #2

In a second sneak peek video from episode 9, Hanna gives Alison the cold shoulder while leaving class – and Alison doesn’t understand why. Hanna’s been upset since Alison’s return, but the latest stunt that Alison pulled involving a fake attack at Hanna’s house pushed her over the edge.

“It’s not about the window,” Hanna yells at Alison in the video. “Your stupid stunts affect a lot of people.”

Alison still doesn’t get it, leading Hanna to tell her to stay with one of the other girls until her father comes back from his trip. But Hanna’s outburst makes Alison realize that she’s losing her friends.

“What’s happening to us?” Alison asks, scared. “Our group is falling apart.”

But before Alison could go any further, the pair is interrupted by another student in the classroom – Jenna.

Sneak Peek #3

It looks like “A” is getting to Alison. Thanks to the arrival of Detective Tanner, the teen is frantic when she finds Spencer in the hallway. Spencer blows Alison off, but Alison warns her, “If one of us falls, we all fall.”

Sneak Peek #4

Detective Tanner is onto Aria. A fourth sneak peek video from episode 9 shows Aria and Ella inside Tanner’s office – and she wants to know all about Ezra. The detective begins to question Aria about an “intimate relationship” with Ezra, but is cut off by a protective Ella.
