"Pretty Little Liars" fans are bound to experience the shock of their lives on Tuesday night's summer finale.

The episode, which is being dubbed as "fatal finale" guarantees that at least one well-loved character will die, according to TV Line.

Multiple sources previously revealed that none of the four pretty liars will die, at least this season, but one of their loved ones will most likely will.

Last week, Caleb opened up to Hanna about his trip to Ravenswood and now fans are speculating that this will lead to his early demise, Wet Paint reported.

Caleb was previously part of the short-lived series "Ravenswood" and the show's last episode confirmed he was cursed.

After the show ended, no one knew what happened to Caleb exactly, except that he returned to the show and had hard time acting all normal.

On the other hand, fans are also speculating that the death on next week's episode may involve Alison or Mona. However, none of these rumors are for certain because both characters have gone both sides again and again throughout the past seasons, IBTimes noted.

Next week's episode's synopsis read, as published by Wet Paint, "Feeling trapped by Alison and A, the PLLs turn to an unlikely person for help in "Taking This One To the Grave." With Alison leading them down with a dangerous path and "A" barring them from telling the police the truth, Aria, Emily, Hanna and Spencer feel trapped and are desperate to find a way out of this mess. With nothing else to lose, could the PLLs lose everything by putting their faith in a possibly unworthy ally? Meanwhile, Alison begins to build up her own army now that the PLLs have turned their backs on her."

"Pretty Little Liars" will return on August 26 on ABC Family for the summer finale episode. The series will continue this coming December.
