Another brilliant curry-western from Dharmendra (having already done Mera Gaon Mera Desh and Sholay), but this with a lot more of the comedy element. Which is enforced with the help of Johnny Walker and Jagdeep, plus a whole village of comedians (including Mehar Mittal - the King of Punjabi comedy himself).
The film also includes the hit song "Main Jatt yamla pagla diwana" - sung by non-other than Rafi sahib himself. As well as "Uth neend se Mirzeya", a Lata-Rafi duet on the Mirza-Sahiban theme.
On the whole this is a very funny film, which also has its typical serious side too. The story starts off with Dharmendra learning that he is really the son of a wealthy family massacred by Ajit. The nanny manages to escape with him (as a baby) and then brings him up. Upon learning this fact Dharmendra sets upon finding the villain. In doing so, his first confrontation with Ajit leads to a few police officers being killed. After which Dharmendra puts on the uniform and marches into the local village as a Thanaydhaar.
Here he recruits the locals into the police force and teaches them how to use a gun. This is where the fun starts!
As for the romance side of things, Dharmendra falls for (who else??) Hema. Hema, the niece of Ajit finally succumbs to Dharmendra's charms, and hence "Main Jatt yamla pagla diwana". Ram Mohan plays Hema's mute 'adopted' brother.
