Losing It is set in the world of Baldock, local drug dealer and hard man of the Welsh Valleys. When one of his drug-runners, TJ, starts taking his own cut, it proves to be a big mistake. Baldock's reaction is explosive and violent.

Baldock's life is not straight forward. At home sits his dependent, wheelchair-bound father, a WWII veteran who has no idea about his son's drug empire. This taut father and son relationship is the backdrop to Baldock's increasingly desperate need to find and deal with TJ. Looking for TJ, Baldock neglects his father's needs with incendiary results that will change his life forever.
