The GangStars of Bracelet Bay, with their motto "to do good", are visiting Mumbles market when suddenly the weather makes a dramatic change for the worse.
An emergency arises when a young girl falls from her father’s boat into the rough seas. He desperately alerts the Coastguard, and the lifeboats are launched in an anguished search for the young girl.
Brownie and the GangStars hear of the girl’s plight and set off in search.
The young girl is saved in an extraordinary rescue and returned safely to her anxiously awaiting parents. Only a few know how she was rescued, including the local vicar, who now has another secret to keep.
