A wetland outside Ft. Collins, Colorado, becomes the setting for one amphibian breeding season, filmed through its full cycle of freeze, thaw, and freeze again. The film opens with rare neotenic Tiger Salamanders, animals that reach sexual maturity while keeping the gills and aquatic features normally lost at metamorphosis, a genetic quirk the camera catches in close-up as they move through the water. From there it follows toads trying to breed during drought conditions, with dried-up pools cutting into the number of successful clutches, and snakes stationed at the water's edge picking off young amphibians as they emerge. Time-lapse photography carries much of the film, compressing months of wetland change into sequences that show ice retreating in spring, vegetation filling in through summer, and the pond locking over again by winter. There is no host or narrator driving the story; the footage of salamanders, toads, and snakes across one seasonal cycle is the entire argument, built around how many ways a single wetland can decide which animals survive to breed again.
