Shish (Will Smith) has a very accurate grasp of men's weaknesses: when they are courting, they are too eager to get the other person's favor, but they will be clumsy and lose their charm. Shish has mastered a complete and exclusive theory that can help men successfully capture the other person's heart in the first three dates. This set of strategies is comprehensive and practical, and there are detailed guidelines for dining, holding hands, and kissing during the date. This time Shish's client is the fat man Albert (Kevin James). He is gentle by nature, but he falls in love with a popular female star. So a thorough transformation of Albert is inevitable. More importantly, he actually falls in love with Sarah (Eva Mendes), the female star's assistant reporter, at work. This dating guide who has always been vacant in his own feelings began to taste the breath of love. However, it seems that love in reality is not the same as what he usually designs. The tried and tested rules of love have lost their effect on him. Perhaps, his knowledge of love is far from being proficient enough.
