Bright Lights, Black Hearts is the twenty-second episode of Ben 10.
Max, Gwen, and Ben are in Miami, at a movie set. Ben is clearly upset about that they aren't at the beach, but Gwen reminds him that they're at a movie set. Gwen gasps and notices Michael Morningstar, while Ben remarks that he doesn't "worship" celebrities. Gwen reminds him of his encounter with Mr. Munch, and a flashback is shown. The flashback ends, and Max asks one of the employees about the location of the film canisters. The employee mentions that they've switched to digital, and he speaks to someone on his earpiece, mentioning how he thinks that Max will work for free. Max walks away with the employee, leaving Ben and Gwen to their antics. Ben and Gwen briefly argue about Morningstar, and that leads to Gwen mentioning one of Morningstar's well-known roles, "The Un-alivers", in which he played Sebastian Belmont, a high school student that falls in love with a character named Jenna. In the film, Sebastian is eventually revealed to be "un-alive" and Jenna is revealed to be a werewolf.
