Toby and Spencer will take a road trip on tonight's new episode of Pretty Little Liars.

But not just any road trip.

The couple will give fans an early peek at Ravenswood, the mysterious town whose residents will be at the center of the upcoming Pretty Little Liars spinoff in October.

What will the couple find there? We don't know. What prompts the trek? We can't say. What is up with the cemetery? And the birds? And the overall creepy vibe? We'll all need to tune in to "Under the Gun" for these answers and more.

Watch the sneak peek now:
