The loved ones of Hannah Baker are seeking justice for her death.

In a new trailer for the upcoming second season of 13 Reasons Why, Hannah's friend Clay Jensen (played by Dylan Minnette), is seen stumbling across a Polaroid placed inside his locker that reads, "Hannah wasn't the only one."

The teen's friend and love interest Hannah tragically committed suicide in season one of the Netflix series, according to the Daily Mail.

After reading the Polaroid image, he turns around and sees a vision of Hannah (played by Katherine Langford) standing right behind him.

"What are you going to do about that?" she is heard saying.

Clay attempts to get to the bottom of things as he sits in front of a pile of Polaroids with friends.

Hannah's parents are so determined to get to the bottom of her death.

"There is nothing left worth having except justice for our daughter," Hannah's mother declares.

Clay is also on a mission to find answers.

"I can't count on anyone else anymore," he says. "I have to do this myself."

"No one's going to get justice for her," he adds.

The trailer also sees the past catching up to Bryce Walker, who sexually assaulted Hannah and Jessica in season one.

In a scene from the trailer, Bryce (played by Justin Prentice) finds the word "rapist" tagged across his locker.

Season two of 13 Reasons Why will premiere on Netflix on May 18.
