Sandra Bullock and Melissa McCarthy have proved to be an unlikely yet brilliant combination.
The success of The Heat depended on the rapport that these two could develop. But "straight- laced" Bullock and foul-mouthed McCarthy pulled it off to create one of the year's funniest movies.
Uptight FBI agent Sarah Ashburn (Bullock) is extremely ambitious but hampered by a complete lack of harmony with her co-workers. In short, they can't stand her.
Desperate for a promotion, she is given a last chance to prove she can work with others. When she's sent out of town to find a drug kingpin, she meets Boston PD detective Shannon Mullins (McCarthy).
Mullins is hard-nosed and down-to-earth, and she is not going to let Ashburn take over her patch.
