Rising idol Elanne Kong stars as Ji, one of six youngsters who occupy the eponymous 6th Floor Rear Flat, the very same flat that housed the now moved-on youngsters from the original Truth or Dare. Her roommates include wannabe singer Kay (Tian Yuan of Butterfly) plus four guys, each played by one half of a singing duo.

The other five friends attend to support Kay, but become bored, and take to chatting on Facebook via their mobile phones. That's when the idea hits them: why not start a "happy funeral business" where people can celebrate the departed person's life rather than mourn their death? Sadly, the group doesn't have the capital to start up such a biz, but they fortuitously run into the owner of a prosperous funeral business, played by Eric Tsang. He agrees to front them $10 million HK dollars if they can draw up a feasible business plan, complete with expenses, projected revenue, and probably helpful pie charts. Can these youngsters get their act together, learn the mysteries of Microsoft Office, and get the $10 million to fund their start-up
