On London's Summerhouse Estate, challenges come in all forms, especially for kids. Thirteen-year-old Ra'Nell (Malcolm Kamulete) finds he has to step up and be a man when his mentally ill mother Lisa (Sharon Duncan Brewster) is suddenly hospitalised. Meanwhile, in the courtyards of Summerhouse Estate a thriving but invisible business is being run by Dushane (Ashley Walters) and his friend Sully (Kane Robinson). Charming, sexy and clever, the 26-year-old Dushane has already run out of things to be - except this'. When he attracts the attention of ex-convict and drug dealer Bobby Raikes (Geoff Bell) he seizes an opportunity to be more, to have more - to be Top Boy. Featuring an ensemble cast of brilliant new talent, Top Boy is Ronan Bennett's new four-part drama about young lives lived on the edge and, for the most part, lived out of sight in east London today.
