Big Age follows a group of four young black-British friends who are in the 'big age' era of their lives. With a backdrop of parental expectation, personal dreams and the crushing reality of maxed out credit cards and with the Nigerian phrase 'at your big age!' ringing in their ears; it's a quipped admonition that can be both loving and mocking, both commanding and encouraging - it is about growing up, stretching up, stepping up.

Sadé, the show's protagonist, has just turned 25, or twenty-thrive - she's unashamedly ambitious, fierce but has moments of spiralling (yet hilarious) insecurity. Sadé dreams of being a writer.

Dela is Sade's best friend - she's an artist who prefers to 'go where her soul flows' and is a free-spirited, sexually liberated, social justice warrior who would do anything for her friend. She's also secretly a very middle-class private school kid who never used to "see colour" (something she is secretly deeply ashamed of).

Zeke is Sadé's unrequited love - a slick-talker and player, full of easy charm and charisma.

Completing the foursome is Tayo, the dry humoured grounding force of the group who seemingly has his life on track.
