Johnny Sexton - the man who pulled the strings for the Lions - gives an intimate insight into the rugby life in Becoming a Lion. As of May 2009, Johnny Sexton was the little-known backup fly-half for Leinster, the chronically underachieving Irish province. But when Felipe Contepomi went down with an injury early in the Heineken Cup semi-final against a dominant Munster team, Sexton came on, nailed a penalty with his first touch of the game, and helped Leinster to a crushing victory. Four years, three Heineken Cups later and one British and Irish Lions tour victory later, Sexton is by some distance the leading fly-half in the northern hemisphere. When the 2013 Lions squad was selected, there was almost universal agreement that Sexton was the most important single player heading to Australia. And over the course of the Lions' first victorious Test series in sixteen years, Sexton was the man pulling the strings. His try in the third test was the decisive blow, and his joyous celebrations after scoring were echoed in homes across Britain and Ireland. Becoming a Lion is an intimate portrait of life at the highest levels of the professional game - at Leinster, with Ireland, and on tour with the Lions.
