Watch Stefanie Scott & Austin Swift in New 'I.T.' Trailer

Stefanie Scott is stunned by what Austin Swift shows her on his phone in the new trailer for I.T.

Taylor‘s younger brother Austin, 24, makes his acting debut in the tech thriller which also stars Pierce Brosnan and Anna Friel.

The thriller centers on tech company runner Mike Ryan, who has everything he could ever want, a beautiful family and a top of the line smart house. The company he owns is on the verge of changing flight leasing forever.

That is, until the relationship with his closest advisor turns nasty, to the point where his teenage daughter is being stalked and his family is under attack through every technological facet of their lives.

I.T. is set to hit theaters in September.
