RALPH CONSIDERS CROSSING A LINE TO DEFEAT THE THINKER
When Barry (Grant Gustin) and Team Flash find a way to enter The Thinker’s lair, Ralph (guest star Hartley Sawyer) considers crossing a dangerous line to defeat DeVoe. Meanwhile, Joe (Jesse L. Martin) is concerned by Harry’s (Tom Cavanagh) recent behavior.
In The Flash, Barry Allen was just 11 years old when his mother was killed in a bizarre and terrifying incident and his father was falsely convicted of the murder. With his life changed forever by the tragedy, Barry was taken in and raised by Detective Joe West, the father of Barry’s best friend, Iris. Now, Barry has become a brilliant, driven and endearingly geeky CSI investigator, whose determination to uncover the truth about his mother’s strange death leads him to follow up on every unexplained urban legend and scientific advancement that comes along.
Based on characters appearing in comic books and graphic novels published by DC Comics, THE FLASH is from Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television.
