Infidelity 101 follows Shihoo, a man who thought he had it all – a solid new job, a six–year marriage to his stunning wife Shia, and a life that looked perfect from the outside. But when he starts to suspect that Shia is cheating, the doubt eats away at him. Unable to shake the paranoia, he confides in his attractive coworker Mina… who offers him a solution of her own: why not have an affair too? Shihoo knows it’s wrong, but with his wife acting more suspicious than ever and gorgeous women all around the office, his resolve starts to crumble. If Shia really is unfaithful, is it still cheating when he does the same – or is he about to fail Infidelity 101 in the messiest way possible?
