Keith Tapscott's is in Plymouth he should spot your post, I'm not sure who else lives there. Welcome to APUG BTW.

You can get film in Plymouth but it'll depend on what you want & the format. I'm sure you could either pre-order if needed or get some sent to where you're staying. It's not a huge city and UK towns/cities have much more defined centers than US equivalents.

A trip out onto Darmoor is well worth a day away from the city
