The fifth season returns to new events, as the Leverage crew is helping a new mission for the son of a veteran hockey player who believes the team management is not looking for his father's health. Perhaps it may be the opposite, where there is the discovery of real management intentions more grim.
I read somewhere that Leverage is too airy a show and that it would do well to rein in its wilder flights of fancy, but I think a show as silly in its bones as this can use all the wild cards it can find in its sleeves.
