A tough police sergeant's mother comes to visit him, and promptly starts trying to fix up his life, much to his embarrassment. For his birthday she buys him a machine gun out of the back of a van, and begins to further interfere with his job and love life, eventually helping him with a case he's on.

Thoroughly witless and thuddingly unfunny, Stop! Or My Mom Will Shoot gives its mismatched stars very little to work with - and as a result, they really don't work.

'Stop! Or My Mom Will Shoot' delivers charming, lighthearted entertainment elevated by Estelle Getty's engaging performance and some memorable dialogue. However, the film suffers from a dire, formulaic script with predictable plotting and shallow, stereotypical characters. The comedy proves divisive, with some finding genuine laughs while others consider it completely unfunny. Chemistry between Stallone and Getty receives mixed reactions. Despite its flaws, some viewers appreciate it as harmless escapist fun, though many found it boring and forgettable.
