Shen Chumo, a down-and-out talented female painter with "hyperamnesia" and an absolute sense of color, was framed by her hypocritical fiancé and lost everything. In order to find out the truth about her life experience and clear her suspicions, she took the initiative to approach Gu Chen, the upright but also good criminal investigation captain. Shen Chumo used his amazing painting talent to assist the police in criminal profiling and repeatedly solved strange cases. In the process of "Strategy" Gu Chen seeking asylum, she was captured by Gu Chen's top cooking skills. The two team up to fight against the bully forces behind them and the serial killer who is good at cold weapons. The ex-fiancé bursts into tears and begs for reconciliation (chasing his wife in the crematorium). In the end, Shen Chumo uses his paintbrush as a blade to uncover the city's evil network and gain justice and true love.
