Former policeman Ray 'Sugar' Leonard is no stranger to bad breaks. But even Walter White never had to open up and share his feelings with a bunch of misfits like Ray's chemotherapy group: a giant God-bothering Welsh bouncer a sharp-suited wannabe Wolf of Wall Street and a misanthropic potty-mouthed little old lady. Compared to that lot getting mugged on his way home from the clinic was almost a relief. But Ray is not your average victim. And when his training kicks in and his would-be attacker winds up dead he wonders who else might be equally deserving of such summary justice? After all he's got cancer what's he got to lose? Then Ray lets slip his new philosophy to the group and it soon becomes clear that he's not the only one with murder in mind. . .
