What's next on Suits season 4? SUITSonUSA/facebook

Suits season 4, episode 14 titled Derailed airs this Wednesday (18 February) on USA Network and looks like Mike and Donna are up to something "sketchy" behind Harvey's back.

After last week's episode, where a lot of personal issues between Louis and Mike got resolved, the team is now ready to take on real-deal cases and, of course, win in whatever way possible. "In the upcoming episode, the focus is on Mike as he takes a case that hits close to home," reports Christian Today.

The official synopsis of Derailed reads:

"When Mike takes a humanitarian case with the potential to jeopardize firm business, Harvey must decide how much to rein in his associate. Meanwhile, Jessica wrestles with the distance she's been forced to put between herself and Jeff Malone. And Louis fights to get the respect a name partner deserves."

In the new episode's promo (video below), Harvey is heard saying, "You did something sketchy" and Donna will be seen going in to file cabinets and then looking very worried. Meanwhile, Mike is heard saying: "If Harvey figures out what is going on, he's gonna pull the plug."

Viewers can reportedly also expect to find out if the lie Jessica told Jeff is going to take a toll on their relationship.

Suits season 4, episode 14 airs tonight, 18 February at 9pm ET on USA Network.
