A man wakes up in the desert, handcuffed and with a hood over his head and a scrap of paper in his pocket with only a name on it. A young single mother who lives in the middle of nowhere finds him, takes him home and nurses him back to health, where they start to fall for each other a little.

But he has no idea who he is, how he woke up bound in the desert or who the name on the paper is, so he goes to the city to try and figure out what's going on, discovering another life seemingly completely separate from who he fells he is now.

An overly-friendly manager of a dingy hotel, a mysterious woman who might have been his lover and more swirl around his eternally confused expression, and before we're given much idea about what's going on, suddenly he's waking up in the desert with a hood over his head all over again.

It's then you realise you're kind of sort of watching a sci-fi movie about the nature of past, future, identity and memory rather than a domestic drama with some mystery elements. To the film's detriment, it poses all the questions about memory, etc, but doesn't make much effort to answer them. The final sequence – a promotional video from a pharmaceutical company – makes it seem like there's a much bigger story behind what you've just seen that the creative team just didn't have the ambition or money to explore.

Pig certainly has a sense of narrative audacity – the structure is like nothing you've ever seen before, if nothing else. But the lead actor (referred to as 'Man' in the credits) is so emotionless you're not taken on the journey with him, you just spend an hour an a half watching a guy being confused. Beyond that, there just feels like there's too much missing.

And I still have no idea what the title refers to. Maybe he was a guinea pig for memory experimentation?
