Set in noughties Britain, Mouth to Mouth deals with six young adults as they enter their twenties and realise that there is more to status than a Facebook update. Each year-in-the-life episode concentrates on one character's story as their lives intertwine and sometimes collide. Small events have big effects and molehills become mountains, as each of them scrabble to find their way and discover that be it comic, tragic and unpredictable, modern life can be tough. Wannabe entrepreneur Rakim Prateek spends his days dreaming of being the next Alan Sugar and defeating the bullies that have blighted his life. After another beating, he is offered a solution by Tahir, the coolest kid at college. But there is a price to pay for protection and Rakim quickly finds himself in a world of guns, drug dealing and violence. Seduced by the power, Rakim gets deeper, until the consequences of his dealing hit him square in the face.
