Set in a beautifully recreated 1930's Shanghai, Junchu has fallen into a profound state of depression after witnessing his girlfriend's tragic death on the day he was set to propose. Unable to forget Manli, and living in a tortured state of denial and guilt, Junchun's domineering mother decides to marry him off to Sansan, a beautiful young woman who she believes will lift her son's spirits. The marriage starts off loveless and unconsummated, but Sansan is determined to win his love. One day the ghost of Manli, still pining for her former lover appears to Sansan. The two quickly strike a deal; Manli will help the new bride, but only if she can temporarily enter Sansan's body so that she can reconnect physically with her former lover one last time. The plan goes too well and as Junchu begins to fall in love with Sansan, Manli turns from friendly and helpful to jealous and vengeful.
