What is love? Is it something spiritual or wholly physical? Can our feelings be explained and quantified? Or are we all actually two halves of a whole?

Ask Alice and Luke and you'd receive vastly different answers.

Despite her world having been recently dismantled by a messy break-up, Alice would tell you that love is the most important ? albeit ineffable ? human experiences. But when she once again crosses paths with her old school nemesis, Luke, he challenges this. Luke is a scientist and he's certain love can be measured and explained ? just like everything else.

So the two decide to make a bet: they'll each venture back into dating and if one of them falls in love, Alice wins, if not, then Luke does.

But can anyone win when you're playing with emotions?
