Polizistin Aysa is a very cheerful rookie. She really wants to show us her self cuffing and self unlocking techniques. She has done it many times before and she says it is very easy. But she is forgetting she only practised this skill with chain handcuffs, not with her hinged cuffs! It's easy with chain cuffs, even with the keyholes on the wrong side. And with hinged cuffs, you just know the classic error is waiting to happen... Can Aysa escape?
