Doe (2018)

John is a brilliant linguistic scientist with a loving wife and daughter but with a massive gap in his life. Eight years ago, he turned up out of nowhere, with no memories except a recurring dream. He is sent tumbling down the proverbial rabbit hole after meeting a man that shares a similar condition and learning that there are more like him, all amnesiacs with extraordinary abilities. He convinces his brother-in-law, private investigator Carl, to help him uncover his true identity before his past can rise up to destroy him and his family.
