After solving his brother';s murder in Season 1 of Reacher, the titular character finds himself immersed in the middle of a big conspiracy. Based on Bad Luck and Trouble -- the 11th novel in Lee Child';s series -- the second season of the TV series kicks off with Jack Reacher (Alan Ritchson) reuniting with his former 110th Special Investigation Unit, an army team he hand-picked to crack the toughest cases. It turns out one of their colleagues has been brutally murdered, and the rest of the squadron might be targets too.
