"Pretty Little Liars" season 7 will prove that the girls may be incapable of keeping a secret, especially if that secret has something to do with someone's death.

In the trailer for the upcoming season of the mystery thriller, the girls appear to be burying a dead body. Emily confesses she "can't live with this" and cries about the severity of the situation.

Spencer, on the other hand, tries to convince herself that "there is no other way," although it is apparent in the "Pretty "Little Liars" season 7 trailer that she is just fighting through the fear.

Spencer mentions something about a plan going awry. Whatever this plan is, which definitely has something to do with saving Hanna, led to a casualty they did not expect.

There are reports, however, that they were burying the dead blonde hanging at the church tower. It is unknown if it is Hanna, but fans are not convinced that the liar is already a goner.

Some speculations say that the body in the church belongs to Sara and not Hanna simply because "Pretty Little Liars" would not want to let go of its main character, at least not yet. That does not mean that Hanna is out of harm's way.

Meanwhile, in "Pretty Little Liars" season 7, Alison will also be in big trouble. The trailer shows Rollins go full Hannibal complete with his tools he intends to use to torture his wife. Thankfully, it looks like Aria will be there to save the day.

Another haunting bit in the trailer is Mary Parker's warning to Spencer to lock her doors because they are "no longer safe these days." She said this with a smile, which gave the impression that she likes it that way.

"Pretty Little Liars" season 7 premieres June 21 at 8 p.m. ET on Freeform. Here is the description for the episode:

After Hanna's shocking abduction by 'Uber A,' the PLLs and company desperately race against the clock to save one of their own. The only way to do this is by handing over evidence of Charlotte's real murderer to 'Uber A.' In order to do so, the girls must decide what blatant lines they are willing to cross that they have never breached before; and once they cross that line, there is no turning back.
