The Invention of Sophie Carter

1851. Bounced from one home to another their whole lives, orphaned identical twins Sophie and Mariah Carter have always relied on each other for love and support, even though the sisters couldn't be more different.

Brash Sophie wants to be an inventor, and demure Mariah wants to be an artist. Both long to visit London for the summer - Sophie to see the Queen’s Great Exhibition and Mariah to study the world’s finest collection of paintings. But when their cantankerous aunt answers their letter pleading for a place to stay, she insists she only has time and room to spare for one of them.

So, Mariah and Sophie hatch a clever scheme: They will travel to London together and take turns playing the part of "Sophie".

At first the plan runs like clockwork. But as the girls avoid getting caught by increasingly narrow margins and two handsome gentlemen - both of whom think they’re falling in love with the real Sophie Carter - enter the equation, the sisters find they don’t have the situation quite as under control as they thought.
