Kevin Hart plans to marry his on-screen girlfriend in the trailer for the upcoming comedy, "Ride Along". There's just one problem -- he first has to get her brother's blessing. That would not be such an issue if her brother were anything other than a crazy cop played by Ice Cube, TheWrap said.

James (Cube) offers Ben (Hart) a deal: He'll give his blessing, if Ben can hang on during a wild ride through the mean streets of Atlanta. That sounds good to Ben, a security guard who recently enrolled in the police academy.

But the 24-hour patrol turns out to be a lot more dangerous than the man who regularly polices a high school cafeteria bargained for.

"Ride Along" also stars John Leguizamo, Bruce McGill and Jay Pharoah. The buddy comedy comes out Jan. 17.
