Synopsis：At 8 a.m., private detective Long Fei wakes up in his Shanghai home to find that the woman lying beside him is his maid Mengyao, not his wife Shen Peipei. Mengyao insists she is Long Fei's wife, and Shen Peipei is the maid. While he is still baffled, his sworn brother Hou Fang suddenly bursts in with a group of men, demanding gold. When his demand is refused, he shoots Long Fei dead. Stranger still, Long Fei awakens again at exactly 8 a.m. But this time, not only has the person beside him changed, but his identity has also shifted from a detective to an accountant who stole gold from the bank, and his wife Shen Peipei is now both the maid and his mistress. Wife, lover, brother, gold—mysteries pile up. Through repeated cycles of life and death, Long Fei gradually unravels the truth one thread at a time...
