Big Time Rush, Gustavo, Kelly, Mrs. Knight, and Katie visit Rosewood, PA to perform at Spencer Hastings' start-of-summer party. What happens after both Alison DiLaurentis and Kendall Knight go missing? Logan/Spencer, Carlos/Aria, James/Hanna. Didn't even realize there was a story already called Big Time Liars, so I changed it. :)

Lame title. Big Time Rush have stay in Rosewood for almost 2 years. Meanwhile, the Pretty Little Liars got mystery texts from A, who they assumed it was Alison, their friends who went missing for almost a year. BTR help PLL girls to solve the mystery. A lil' bit romance, i think Logan/Spencer and Kendall/Aria.
