Delivery boy Chen Mo was forced to sign a special contract - randomly playing a "high-risk identity" every month, from a death row prisoner to a cult leader, from a runaway agent to an alien spy. Each time you play an identity, you will gain a permanent ability of that identity. And when he gathered all seven identities, a shocking secret surfaced: he was not "acting" these identities, but "recycling" slices of his own life. The real him died seven years ago.
