Ann and Alice Hartley, both 23, were born into a middle-class family of office workers. These twins, despite their fair share of arguments, share an unspoken connection that goes beyond words. They seem to have a unique ability to read each other's thoughts, and, more often than not, you'll catch them talking in sync, almost like a secret language only they understand. While they have their differences, there's a special bond that ties them together, making them more than just sisters.
