Teenage sisters Charli and Lola are on the verge of an experience beyond their wildest dreams! Pack your bags and jet off to Rome as the girls start their summer internship working for the legendary Derek Hanson - the totally cool international tycoon whose empire reaches from airlines to cutting-edge fashion. Amid the fabulous sights of this exciting city, the girls do their best to impress their boss, while still finding time to design their own line of very hip clothing, meet some very cute guys and turn their summer abroad into one awesome adventure they - and you - will never forget!
Unfortunately the movie When in Rome is not yet available on HBO Max.
