Riders: Catch Tomorrow (라이더스: 내일을 잡아라)

Cha Ki Joon (Kim Dong Wook) is a well-educated young man who begins his career in an enviable entry-level job at a large corporation. But he is not happy with his life. On a whim, Ki Joon decides to quit his job and start up a new business with his two childhood friends, Yoon So Dam (Lee Chung Ah) and Go Tae Ra (Choi Yeo Jin).

So Dam has been working lots of different part-time jobs while trying to make it as an illustrator. Tae Ra is a former cycling athlete who decides to go in with Ki Joon on his new business idea – because it’s a company that will make rickshaws, of all things. As the three friends deal with the real world, changing friendships and budding relationships, can their crazy business possibly succeed?
