ABC Family’s highly-touted new series, Pretty Little Liars, debuts tonight. The pilot episode will repeat back-to-back-to-back in a three hour mini-marathon starting at 8pm EST. The program, based on the book series by Sara Shepard, details a group of four friends who find their secrets exposed by a fifth friend who’s supposed to be deceased. Pretty freaky.

The cable network has picked the series up for a 10-episode run, standard procedure for the channel. Massive promotion suggests ABC Family’s faith in Liars, but only Tuesday’s premiere will reveal how the fans react.
