When their estranged childhood friend turns up dead, best friends Frankie and Tabitha find themselves at the mercy of a dangerous, yet clumsy villain, who begins sending them mysterious messages. Although our liars--not all that different from the characters on Pretty Little Liars- would much rather lie in bed than fend off a killer, they'll do it if they have to, they guess. They can't trust anyone except each other, which is fine, because they don't really want to hang out with anyone else anyway.
