Behind the Mask - Season 1

Lookkaew is a hi-so woman who is cheating on her boyfriend, Ratt. Her boyfriend catches her and walks away. When Lookkaew goes after him, she gets into a car accident and hits a girl named Natda. Lookkaew's selfish mother doesn't want to lose Ratt as a son-in-law because her daughter is in a coma and may not wake up. To fool Ratt and his father into continuing with the marriage, she has the unconscious Natda undergo plastic surgery to look like her daughter, Lookkaew. Natda wakes up and is told she is Lookkaew, but she has no memories except for what she is told by her fake mother. She also has to deal with Ratt who is angry and hurt because the real Lookkaew cheated on him. Nothing in her life feels familiar to her and even Ratt notices her personality change. Will Ratt find out the truth? Will Natda get her memories back? And what happens if the real Lookkaew wakes up?
