"We are a group of friends located in OKC who are trying to make a movie about a retired police car and a reluctant hero who purchased him. We think the script is creative, funny and heartwarming. [...] If you'd like to see a full-length feature film called C-RAP (Car-Remote Automated Police), and you have ideas for helping us, drop us a line...we'd love to hear from you."
