Next best is £5.49 at HMV. This is a very recent film (2010), so this may be a mistake by Play.
Spencer Aimes (Ashton Kutcher - Valentine's Day, What Happens in Vegas) is just your average, undercover, super-assassin accustomed to a life of flashy sports cars and even flashier women. But when he meets Jen Kornfeldt (Katherine Heigl - The Ugly Truth, 27 Dresses), a fun-loving computer tech, he finds true love... and happily trades international intrigue for domestic bliss.
They are enjoying a picture-perfect marriage - that is, until they learn Spencer's the target of a multi-million dollar hit. Now Spencer and Jen are on the run and they must find out who wants Spencer dead and why, all the while trying to save their marriage... and just plain survive.
