Ritchie is a Glaswegian chancer with low hopes and no prospects. Disillusioned with city life, he goes undercover at a Highland conservation centre to make his fortune as an illegal pearl fisher with the help of his two hapless and accident prone mates, Danny and Fraser.

After the success of pearl fishing attracts the unwanted attentions of old school Glaswegian mobster Gavin and his work at the centre leads him to question his true motivations, Ritchie must risk life and limb to save the Highlands from ecological disaster and win Beth's heart...
