Just because he's an assassin, doesn't mean he's an ass! Lassiter is an elite assassin who consistently strives for perfection. To that end, he installed therapy software that guaranteed he'd improve in every way. The A.I. therapist, Norman, has noted that Lassiter is making positive strides. Lassiter doesn't quite agree, though, as he's pretty confident his speed and efficiency are declining. So is his judgment... In fact, he's suddenly grown a soft spot for hard-luck cases. This lands him with a brand new employee named Biff, who challenges his authority at every turn. The guy happens to be a great cook, though, and living on protein bars isn't exactly fine dining. The two head after their next mark, a person-pickup who turns out to be an unexpected fugitive, and she puts Lassiter's ship on the radar of the Feds. More concerning, though, is that she also lands them in the path of a psychotic, exceedingly wealthy, martial arts expert who wants nothing more than to see them all dead. That's when Biff shows he can do more than cook, and also teaches Lassiter that he's in desperate need of hand-to-hand combat skills.
