28-year-old Jack has mysteriously started shrinking, and his 26-year-old sister Alice has taken it upon herself to care for him.  She's been taller than him since they were teenagers, but now it's getting a little ridiculous -- at 5'11, she's a full 8 inches taller than Jack, which is only increasing by the day.  They manage to keep their domineering mother, the formidable 6'3 Sadie, in the dark about what's going on, but of course she finds out eventually.  She then decides to move into Alice's house, to help her daughter care for Jack.  There's some inevitable tension, but overall Jack is well taken-care-of.  His grandmother, the fun-loving and flirty 6'3 Elena, arrives to spice things up.  Everything seems ok, but the only thing is...Jack's shrinking doesn't seem to be stopping...
