Tom is 29 and a management consultant. To be precise: he is a numbers nerd. But a likable one. In search of the perfect partner, he finds himself caught in the algorithm-driven clutches of a dating site, which actually presents him with the perfect woman: 94 percent match - Lisa is the one. Unfortunately, only her eccentric mother shows up for the first date. Tom meets Lisa elsewhere. And this first encounter does not go at all as he had imagined. Just as Tom is about to come to terms with his bad karma, his friend Joshi enlightens him: "Why should life give you gifts if you never do anything for others?" Tom resolves to apply Joshi's formula for happiness and to bring joy to friends and strangers for 28 days. With each gift, Tom's life spirals further out of control. Will he really be able to convince Lisa of the secret magic of the percentage?.
